Summary: The biofabrication of structural proteins with controllable properties via amino acid sequence design is important for biomedicine and biotechnology. However, a complete framework connecting amino acid sequence to material properties is currently unavailable. This study developed a model to classify a library of de novo elastin-like polypeptides (ELPs) based on their thermoresponsive properties, providing a pathway for accelerating the design of de novo ELPs with specific phase behavior and material properties.

Summary: Chitosan hydrogels were prepared by freeze-drying at different concentrations and molecular weights, and sodium bicarbonate was used as a crosslinking agent for physical crosslinking of chitosan sponges. XPS analysis confirmed the physical crosslinking of chitosan hydrogels using sodium bicarbonate. The chitosan hydrogels exhibited semi-crystalline nature, highly porous structure, high water absorption, and thermal stability, as well as non-cytotoxicity towards HT29 cells. Therefore, physically crosslinked chitosan hydrogels show great potential as biomaterials for biomedical applications.

Summary: This study introduces a series of rationally designed collagen-like proteins that can form self-supporting gels and exhibit noncytotoxicity in cell-culture assays. As the triple-helical domains are lengthened, the gels become less stiff, pore sizes increase, and structural anisotropy decreases. Variations in the protein primary structure, such as cross-linking density and association energies, define the gelation of the protein network.

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.

Summary: The insertion of rigid aliphatic or aromatic building blocks in polymer structures is an effective way to synthesize high -Tg polymer materials. In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.
