Summary: In this study, conductive and superhydrophobic silicone rubber composites with a uniform concave-convex structure were prepared by filling carbon nanotubes in the silicone rubber matrix and using a 2000 mesh screen template replication method and spraying technology. The silicone rubber composite showed good electrical conductivity at 200% elongation and after 500 times of torsion. Additionally, it exhibited good droplet bounce, anti-icing, and self-cleaning properties.

Summary: The research team prepared a superhydrophobic NR film with high water repellency and abrasion resistance through a two-step process, which showed no effect on the glass transition temperature and antimicrobial activity of the film. The film effectively inhibited the formation of bacterial biofilms and maintained high hydrophobicity for oil/water separation applications, with a high separation efficiency.

Summary: The superhydrophobic surface of silicone rubber was prepared through a simple process, giving it excellent superhydrophobic, low adhesion, and self-cleaning properties. The surface showed high contact angle and low rolling angle with water, and even when immersed in water, it remained unwetted. Additionally, it exhibited excellent properties with various hydrophobic solutions.

Summary: In this study, a solvent evaporation-induced self-assembly method was innovatively proposed to produce superhydrophobic surfaces (SHS) with facile prepared, environmentally friendly, and ultrafast ambient temperature curable properties. The surface superhydrophobicity and morphology of the SHS can be readily tuned by varying the spraying concentrations, diisocyanates, solvents, spraying heights, and molecular weight of PDMS. The formation mechanism of the SHS was investigated through small-angle scattering and X-ray photoelectron spectroscopy.

Summary: A simple physical deposition method is used to deposit Al2O3 particles on the surface of RTV silicone rubber to achieve a superhydrophobic surface, with a contact angle of 156.6 degrees and a rolling angle of 5.1 degrees. The surface roughness is increased via Al2O3 particles, leading to remarkable self-cleaning and droplet bounce properties on the prepared surface.

Summary: The effect of superhydrophobic surface on the surface electrical properties of silicone rubber composite insulators was studied. It was found that changing the surface structure of the composites altered the distribution of surface traps. The superhydrophobic sample had higher energy level and density of deep traps compared to the common sample, which effectively inhibited electron avalanche and increased the surface flashover voltage.

Summary: This study investigated the effect of aluminum nitride (AlN) on the self-cleaning and bouncing properties of room temperature vulcanized (RTV) silicone rubber by preparing a superhydrophobic AlN/RTV composite with micro-nano structure. The results showed that the micro-roughness structures formed on the RTV surface by AlN contributed to the outstanding self-cleaning and bouncing properties of the samples. The static contact angle and rolling angle of AlN/RTV were found to be 157.7 +/- 0.9 degrees and 4.2 +/- 0.7 degrees, respectively.

Summary: A modified melamine polyphosphate (H-Ni@MPP) was successfully obtained by introducing Ni2+ and silicon resin, and expandable graphite (EG) was used to enhance the flame-retardant ability of silicone rubber (SR). The highest flame retardancy of SR/H-Ni@MPP/EG composites was achieved at a loading of 40 phr, and the water resistance of SR composites was also improved after water treatment.
