Summary: This study investigated the double stimuli-responsive properties of PNIPA and PVIM block copolymers in aqueous solutions for the first time. The synthesis of two different block copolymers was performed using RAFT polymerization. The conformational behavior and self-assembly ability of the polymers were found to depend on the location of hydrophobic groups derived from the RAFT agent within the chain, as well as the length and charge of the PVIM block.

Summary: Due to their versatility, superhydrophobic materials have garnered significant attention in power electronics, transportation, engineering, and other fields. The volume fraction of fluorinated silicon oxide nanoparticles is a crucial factor in these materials. Increasing the volume fraction decreases the stability between the coating and the hydrophobic surface, resulting in a gradual decrease in flashover voltage and a significant increase in voltage dispersion after 30 vol.%. This study proposes a self-assembly strategy based on surface energy differences, utilizing boron nitride nanosheets and silicon oxide nanoparticles as a binary filling phase in the coating. Experimental results demonstrate the optimization of the superhydrophobic coating's flashover voltage using this binary filling phase coating, providing new ideas for filling phase selection and application of superhydrophobic materials.

Summary: Polymerization-induced self-assembly (PISA) is an effective method for preparing block copolymer (BCP) particles with various morphologies, but the preparation of BCPs with inverse bicontinuous phase structure via PISA is rarely reported. In this study, particles with inverse bicontinuous phases were successfully prepared using PISA in ethanol/water. The bicontinuous structure of the BCP particles was characterized by transmission electron microscopy, and the effects of solvent composition and the degree of polymerization of the core-forming block were investigated.

Summary: Photoresponsive Cu nanoclusters with atomic precision were prepared using an azo-containing ligand, demonstrating light-triggered reversible self-assembly into nanofibers in a binary solvent mixture. UV irradiation caused the originally straight nanofibers to bend due to the isomerization of the peripheral azo groups, while exposure to visible light resulted in the reformation of the nanofibers. This light-triggered, reversible morphological change process could be repeated at least three times, showing the high reversibility of Cu nanoclusters' behavior.
