Summary: In this study, biocompatible ultrafine fibers based on talc nanosheets (TNS)/PVDF composites were fabricated, showing robust electromechanical responses. Piezoresponse force microscopy (PFM) was used to analyze ferroelectric and piezoelectric coefficients. The 0.5 wt% TNS dispersed ultrafine fibers exhibited well-defined ferroelectric characteristics with an enhanced piezoelectric coefficient (d(33)) of approximately 43.3 pm/V. The piezoelectric coefficients strongly depended on the morphology and electroactive phase fraction of the composite ultrafine fiber. In vitro cytotoxicity tests showed that the TNS/PVDF composite ultrafine fibers had no cytotoxic response and promoted cell viability. These TNS/PVDF piezoelectric ultrafine fibers are thus suitable for bioelectronics applications, especially as flexible wearable electronic devices and sensors.

Summary: In this study, polylactide nonwovens were made electrically conductive by coating them with multiwall carbon nanotubes (MWCNT) via padding and dip-coating. The presence of MWCNT on the fiber surfaces formed an electrically conductive network, resulting in different surface resistivity (Rs) depending on the coating method. Etching the nonwovens with sodium hydroxide affected the surface roughness and led to changes in Rs, with padding increasing Rs and dip-coating decreasing Rs. Scanning electron microscopy confirmed the presence of MWCNT, and impedance spectroscopy showed the dominant role of the MWCNT network in the electrical properties of the nonwovens.

Summary: In this study, PLLA/ZnO oriented fibers were prepared through orientation electrospinning for a piezoelectric generator, eliminating the need for polarization and stretching post-processes. The resulting composite fibers showed macroscopic orientation, molecular alignment, increased crystallinity, and a higher polar phase for PLLA. The generator exhibited significant and stable piezoelectric signals over 1000s, increasing the open-circuit voltage to 7.9V, nearly 4.6 times larger than that of the random neat device. The oriented fibers and ZnO-induced stress concentration contributed to improved piezoelectricity, as confirmed by simulations. Additionally, the generator successfully charged a 10μF capacitor up to 2V at 210s and illuminated a LED, demonstrating its potential as a wearable self-powered sensor for monitoring human movement and health.

Summary: Expanding the range of materials for extrusion-based 3D printing is crucial for advanced applications. The goal is to achieve higher temperature resistance while maintaining strength. A new commercialized filament based on polyester with increased glass transition temperature has been investigated for its effect on interdiffusive welding process. Despite the expected detrimental impact, the results suggest that polymer chain stiffness plays a crucial role in limiting residual molecular anisotropy, resulting in similar weld strength compared to a co-polyester with lower glass transition temperature.

Summary: The structural evolution of poly(butylene succinate) (PBS) crystals was studied using synchrotron wide-angle and small-angle X-ray scattering (WAXS and SAXS) analysis after crystallization at 100 degrees C. Isothermal crystallization of PBS resulted in a single lamellar population. The temperature-dependent WAXS/SAXS analysis revealed the development of an additional crystal population characterized by thicker lamellae upon heating, leading to a dual lamellar population. The derived temperature dependence of the lamellar thickness for the two different crystal populations provided structural information that elucidated the multiple melting behavior of PBS.

Summary: This Feature Article discusses our recent research on the nucleation and crystallization of semi-crystalline polymeric droplets dispersed in immiscible matrices. The overall crystallization kinetics of the droplets can provide insights into the contributions of nucleation and growth. By defining the Turnbull number, we can determine the relative importance of nucleation versus growth. Examples are shown where the overall kinetics is dominated by crystal growth and examples where nucleation controls the crystallization. The strategic use of self-nucleation and the role of interfacial roughness and heterogeneous nucleating agents are also discussed. Overall, studying the kinetics of different droplet dispersions contributes to the fundamental understanding of polymer nucleation.

Summary: The inter-phase migration of nucleating particles and their effect on the fractionated crystallization of polypropylene droplets dispersed in a polystyrene matrix were investigated. The nucleating agents show a concentration-dependent increase in the high-temperature crystallization peak at the expense of reducing the low-temperature peaks. Surprisingly, the most effective nucleating agents have a higher nucleation efficiency when initially added to the polystyrene phase rather than the polypropylene phase. The migration of particles from the polystyrene phase to the phases' boundary or the polypropylene droplets is explained by considering the dominance of kinetic factors.

Summary: This study investigates the molecular and chemical-physical properties of collagen extracted from Chondrosia reniformis sponges collected in different seasons to evaluate the potential impact of sea temperature. The results show that collagen fibrils extracted from samples at 17 degrees C have lower lysyl-hydroxylation level, thermal stability, and protein glycosylation level compared to those extracted from samples at 27 degrees C. Membranes made from 17 degrees C fibrils exhibit higher stiffness than those made from 27 degrees C fibrils. The differences in collagen properties are important in guiding the use of the biomaterial.

Summary: This study investigates the effect of incorporating a second comonomer unit in the crystalline unit cell on the melt memory effect of a major component in a random isodimorphic copolymer. It is found that even small amounts of the second comonomer unit significantly reduce the melt memory effect of the copolymers. This reduction is attributed to the disruption of intermolecular interactions and the reduction in self-nucleation capacity caused by the incorporation of the second comonomer unit in the polymer chain.

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 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.
