Summary: In this study, the effect of boron doping concentration on the wettability and surface free energy (SFE) of polycrystalline boron-doped diamond (PBDD) films was investigated. Different approaches were used to estimate the SFEs of the films, and it was found that increasing boron doping concentration led to higher SFEs. This study provides a reference for the estimation of SFE using empirical and physics-based semi-empirical approaches.

Summary: Substrate-independent and robust coatings with desired functions are in high demand, but their fabrication and fundamental theory remain challenging due to conflicting requirements on surface free energy (SFE) at different interfaces. A novel strategy based on counterion exchange has been developed to tailor SFE continuously and reversibly. PVDF-g-IL coating with hierarchical surface roughness was fabricated and exhibited excellent bondability and robustness. Controlled counterion exchange was used to tune SFE at the top interface, enabling super-hydrophilic/super-hydrophobic properties and tunable adsorption at multiple interfaces.

Summary: A metallaphotoredox-catalyzed strategy for the aminocarbonylation of alkynes with amines and CO has been developed. This method allows for selective synthesis of alpha,beta-unsaturated amides and a sequential four-component hydroaminocarbonylation/radical alkylation, demonstrating great potential in the selective and divergent functionalization of alkynes. Preliminary mechanistic studies suggest a photoinduced oxidative insertion of aniline and CO into nickel followed by a migratory insertion of (carbamoyl)nickel species may be involved.

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.
