Summary: With the development of miniaturized and highly integrated microelectronic devices, heat dissipation has become a significant concern. Polymer composites with high thermal conductivity and electrical insulation are promising solutions. However, it remains a challenge to achieve both properties simultaneously. In this study, sandwich-structured PVA/BP-BNNS composite films were fabricated to coordinate thermal and electrical properties, with PVA/BP composite films as the top and bottom layers and the BNNS layer as the middle layer. These films exhibited excellent in-plane thermal conductivity, low dielectric constant, and exceptional breakdown strength, making them potentially useful for heat dissipation in high power electronic devices.

Summary: New anion-exchange membranes based on poly(benzimidazolium-imide) containing triazolium groups were prepared using click chemistry for triazolium groups and cross-linking simultaneously. Two different cross-linked membranes with a hydrophilic cross-linker (Q-CLP1) and a hydrophobic cross-linker (Q-CLP2) were tested for mechanical properties. Q-CLP1 showed higher tensile stress due to the rigidity of the aromatic cross-linker, while Q-CLP2 had more fixability and tensile strain due to the aliphatic cross-linker.

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.
