Summary: Covalent adaptive networks combine the advantages of cross-linked elastomers and dynamic bonding in a single system. A simple one-pot method to prepare thiol-ene elastomers that exhibit reversible photoinduced switching from an elastomeric gel to fluid state is demonstrated. This behavior can be generalized to different composition and chemistries and allows for self-healing, remolding, and reversible adhesion.

Summary: In this study, we employed a high-throughput screening strategy to rapidly identify a biocompatible bone adhesive with high bond strength. Through thiol-ene click chemistry, a library of polymers was synthesized and a copolymer (1-S2-FT01) composed of TATATO and PETMP was identified as the most suitable candidate. This copolymer exhibited favorable mechanical properties, supported hMSC adhesion, adhered to bone tissue with similar strength to commercially available bone glues, and facilitated osteogenic differentiation of hMSCs and attachment of polymer scaffolds to bone tissue, making it an ideal alternative bone adhesive for orthopedic surgery.

Summary: Polyurethane (PU) is a commonly used polymer material, but its hydrophilic nature poses challenges to its application in flexible electronic displays. In this study, fluorinated chain extenders were introduced into PU to reduce surface energy and improve surface roughness. This resulted in excellent hydrophobicity and oleophobicity, as well as enhanced mechanical properties through physical cross-linking points.

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.
