Summary: This study investigates the polymer dynamics of weakly attractive polymer nanocomposites, revealing that conformation transition affects the fractional free volume and subsequently the glass-transition temperature and Vogel temperature. The increased monomeric friction is mainly attributed to conformation loss due to adsorption and spatial constraint. The isofriction terminal relaxation time is dependent on the interaction strength, with weak interactions leading to a similar relaxation as bulk PMMA and strong interactions causing an increase in relaxation time due to enhanced entanglement. The decoupling between the relaxation of entangled strands and polymer chains may result from the simultaneous desorption of multiple adsorbed segments.

Summary: The selective distribution of silica nanoparticles grafted with crosslinked PMMA in PMMA/SAN blend was studied. Highly crosslinked PMMA chains mainly located in the PMMA-rich domains, while linear PMMA chains mainly located at the blend matrix interface. NPs grafted with slightly crosslinked chains were partially located at the interface and partially in the PMMA-rich domains. The deviation between theoretical prediction and actual location of modified NPs may be related to the heterogeneity of miniemulsion polymerization. The different locations of modified NPs induced by different grafted chain structures can result in various compatibilization effects on PMMA/SAN blend.

Summary: The objective of this study is to investigate the interaction between acrylic resin and zirconia nanoparticles, and analyze the changes in optical properties and refractive index with incremental loading of nanoparticles. PMMA reinforced with zirconia nanoparticles were prepared using dip coating, spin coating and solvent casting techniques. The spectroscopic and morphological studies provided an overall understanding of the polymer nanocomposite film. The study revealed that the refractive index and optical transparency of the nanocomposite film can be maintained with the incorporation of pure zirconia nanoparticles, and spin coating was found to be the best technique for producing thin films with high transparency and refractive index.

Summary: This study focuses on the detailed characterization of the molecular structure and dilute solution properties of highly dense star-like polymers of poly(methyl methacrylate) and poly(n-butyl methacrylate). The comparison of refractive index increment with corresponding linear homopolymers was conducted. The prepared polymers were characterized using size exclusion chromatography, multi-angle light scattering detector, and online viscometer. The obtained data allowed for the determination of arm distribution, average number of arms per molecule, and molar mass dependency of the draining factor. The relation between the number of arms per molecule and molar mass was estimated and compared with true values.

Summary: The effect of selective distribution and migration behavior of two types of modified nanoclays on the phase behavior of PMMA/SAN blends is investigated. The different grafting density and chain lengths result in different initial locations and subsequent migration behaviors of the nanoclays. The dense and short chain nanosheets are distributed at the interfacial region and form percolation networks, significantly blocking the concentration fluctuation and domain coarsening. The sparse and long chain nanosheets are initially distributed in the SAN-rich domains and slowly migrate to the interfacial region, inhibiting phase separation and stabilizing the morphology.

Summary: This study fabricated sc-PMMA nanorods using various pore sizes AAO templates to investigate its crystallization behavior under nanoconfinement. The results show that the crystallization kinetics of sc-PMMA inside nanopores differs significantly from the bulk state, and the preferred orientation of sc-PMMA crystallites is mainly influenced by the degree of spatial confinement and the polymer molecular weight. This work provides a deeper understanding of sc-PMMA under nanoconfinement and offers opportunities for the applications of supramolecular nanostructures in miniaturized devices.

Summary: Cellulose nanofibrils (CNFs) show promise as reinforcements for polymer fibers, enhancing their strength, stiffness, and fracture toughness. Composite fibers of Poly(methyl methacrylate) (PMMA) and CNFs with varied CNF content were successfully fabricated, leading to significant improvements in mechanical properties. The addition of low-weight fractions of CNFs resulted in increased Young's modulus, yield strength, and fracture toughness in the composite fibers.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
