Summary: The study systematically analyzed the influence of elastomeric poly (octene-co-ethylene) on the crystallization of polyamide 410 in PA-410/POE-g-MA blends. It was found that the elastomer had a nearly unchanged effect on the crystallization rate constant, attributed to the nucleating effect of POE-g-MA and the hindrance effect through the formation of an interfacial network offsetting each other.

Summary: This article discusses the influence of structural relaxation on crystal nucleation process. It shows that structural relaxation has a significant impact on nucleation rate at low temperatures, leading to a continuous increase before reaching a steady state. The study also explains the alleged breakdown of CNT at low temperatures and reveals a significantly lower actual maximum nucleation temperature than previously reported values.

Summary: This study compared the cold crystallization of poly(l-lactic acid) (PLLA) containing α-mesophase with fully amorphous PLLA by mild CO2 treatment. CO2-induced mesophase developed in surface-near regions of the PLLA disks, while the core remained amorphous. Cold-crystallization of CO2-treated PLLA resulted in the formation of conformationally disordered α'-crystals.

Summary: The temperature and strain fields play crucial roles in regulating the fibrous aggregate structure of polyamide 6. Through systematic analysis of oriented polyamide 6 plates, it was found that the stretching process induces the formation of more thermally stable alpha-form crystals, which gradually transform into gamma-form crystals with increasing stretching temperature. Additionally, crystal chips transform into fibrils during the stretching process.

Summary: The effect of uniaxial and biaxial stretching on the structures and properties of stretch-oriented PA6/PA1010 films was investigated. Uniaxial stretching induced the transition from beta-form to alpha + gamma phase and preferred orientation along the stretching direction, while biaxial stretching showed the transition from beta-form to alpha phase and no preferred orientation. The increased stretching ratios improved the melting temperature, crystallinity, and oxygen barrier property of the stretched films. Morphological analysis revealed orientation and deformation of PA1010 particles along the stretching direction without debonding or voids at the interface. The mechanical properties of the stretched films were highly dependent on the stretching ratios, with biaxially stretched films showing significantly higher tensile strength than the cast film.

Summary: The accurate characterization of the interfacial layer is essential for understanding the structure-property relationship in polymer nanocomposites (PNCs). In this study, enthalpy relaxation and interfacial layer properties of model PNCs with attractive interactions were investigated using temperature-modulated differential scanning calorimetry (TMDSC) and broadband dielectric spectroscopy (BDS). Enthalpy relaxation accurately quantified the volume fraction of the interfacial layer, which was consistent with the results from BDS. The parameter (chiint) related to the contribution of the interfacial layer showed similar dependence on nanoparticle loading as the volume fraction estimated from TMDSC. This correlation between enthalpy and dielectric relaxation provides a new approach to characterize the interfacial layer properties and understand the impact on the glass transition behavior in PNCs.

Summary: Polymorphism is a phenomenon in which a substance can crystallize in multiple crystal forms. Organic compounds are particularly prone to polymorphism due to the similarities in molecular conformation or packing arrangement. The reproducible obtaining of specific polymorphs remains a scientific challenge due to the sensitivity of polymorphism to experimental conditions. In this study, the directional crystallization under defined dissipative thermodynamic conditions was applied to control the selective growth of 5-Methyl-2-[(2-nitrophenyl) amino]-3-thiophenecarbonitrile (ROY) polymorphs. It was demonstrated that one of the thirteen polymorphs (OP) can be reliably obtained. The selectivity of this process is discussed in the context of nonequilibrium thermodynamics.

Summary: We investigated the topological barriers in ring polyethylene (PE) melts of trefoil knots and found that these barriers prevent crystallization due to self-entanglement. The topological barriers decrease with increasing polymer chain length (N) and the knotted segments are localized in the noncrystallized region. Our study provides insights into the effects of topology on crystallization in polymer melts.

Summary: Crystal nucleation is a crucial step in the crystallization of metallic glasses. However, the nucleation kinetics can deviate from the classical nucleation theory as the undercooling increases. This study examines the nucleation kinetics in glass and undercooled melt using nanocalorimetry. By varying the cooling rate, the processes of crystallization, homogeneous nucleation, and heterogeneous nucleation are distinguished. The critical cooling rates for suppressing crystallization and nucleation are estimated, and a well-identified amorphous phase is produced for nucleation studies. The underlying kinetic mechanism is revealed through the analysis of crystallization heat and overall heat using the Johnson-Mehl-Avrami method.

Summary: In this study, the isothermal crystallization kinetics of poly(butylene terephthalate) at low temperatures near the glass transition was investigated using chip-sensor fast scanning calorimetry. The Avrami analysis showed that the Avrami index decreased from 4 to less than 2 in the low-temperature peak of the crystallization rate, resulting in significantly low crystallinity near the glass-transition temperature. This phenomenon was attributed to the inhibition of crystal growth by the rigid amorphous fraction (RAF) that is constrained by crystals, as proposed by Schawe for other crystalline polymers. The transformation of the mobile amorphous fraction (MAF) into RAF with the progress of crystallization was confirmed near the glass-transition temperature, leading to the rigidification of all amorphous fractions.

Summary: The application of drugs in the amorphous state is being actively researched in pharmaceutical science to enhance their bioavailability. In this study, the kinetic stability and glass-forming ability of thermally labile quinolone antibiotics were investigated using fast scanning calorimetry. The critical cooling rates for preventing crystallization of oxolinic acid, pipemidic acid, and sparfloxacin were determined to be 10,000, 40, and 80 K·s-1 respectively, indicating their strong glass-forming ability. The Nakamura model was found suitable for describing the crystallization process of the amorphous forms of the quinolone antibiotics using a combination of nonisothermal and isothermal kinetic approaches.

Summary: In the theoretical treatment of crystallization, it is commonly assumed that liquid relaxation processes are faster than crystal nucleation and growth. However, near and below the glass transition temperature, this assumption is often not valid. Deviations from the metastable equilibrium state of the liquid must be considered when determining the kinetic coefficients, thermodynamic driving force, and surface tension of the crystal phase. These factors can greatly influence the overall crystallization process.

Summary: Fast scanning calorimetry (FSC) allows rapid cooling of samples from the melt at rates of several thousand Kelvin per second. By fast cooling at rates of 5000 K s(-1), a perfect amorphous state for polypropylene (PP) can be achieved. In this study, a novel method combining FSC and differential scanning calorimetry was proposed to determine the PP/PE mixing ratio with a standard deviation of 1.4 mass%. The proposed method takes into account the thermal behavior of polyolefin blend components. It is expected to provide a convenient way to analyze the composition of recycled polyolefins without the need for high-temperature solvents or calibration curves.

Summary: The relationship between the changes in the crystallization kinetics and the crystal domains of poly(butylene terephthalate) was investigated under isothermal conditions. The Avrami exponent n characterizing the nucleation and growth kinetics of the crystal domains exhibited a continuous change within the target temperature range, indicating a change in the nucleation mode for spherical domains. The morphology of the crystal domains responsible for this change was identified, with a continuous change in the size of spherulites observed. The formation of 10 nm scale granular nodules with high nuclei density at low temperatures was also observed.

Summary: To understand the properties of glass-forming liquids, the concept of cooperativity length is widely used. Experimental methods of determining this quantity are crucial for the understanding of both thermodynamic and kinetic properties. In this study, the cooperative length and cooperativity number were determined using AC calorimetry and QENS, and the results depended on whether temperature fluctuations were considered. The comparison between the two methods indicated that considering temperature fluctuations is important, and the cooperativity length can be derived from thermodynamic considerations.

Summary: In this study, the glass transition of the biocompatible polymer polyvinylpyrrolidone was investigated using differential scanning calorimetry, fast scanning calorimetry, and broadband dielectric spectroscopy. The dependence of the difference in isobaric specific heat capacities between the liquid and glass on the dynamic glass transition temperature, volume, and number of particles in the cooperatively rearranging regions was determined. A linear relationship between the shift factor from the Frenkel-Kobeko-Reiner equation and the molecular mass of polyvinylpyrrolidone was established. These findings contribute to the selection of optimal excipients for the development of solid dispersions based on amorphous polymers.

Summary: The relationship between changes in crystallization kinetics and crystal domains of poly(butylene terephthalate) was investigated under isothermal conditions. The study found that the nucleation and growth kinetics of the crystal domains exhibited a continuous change within a certain temperature range. This change corresponded to the nucleation mode for spherical domains, such as spherulites and nodules, which depended on whether nucleation occurred from foreign heterogeneities or from the homogeneous melt. The morphology of the crystal domains, specifically the size and formation of spherulites and granular nodules, was identified as a factor contributing to the changes in crystallization kinetics.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.
