Researchers have developed a coating that provides cotton fabrics with stretchable, transparent superhydrophobic properties, enhancing both mechanical and chemical stability for underwater insulation applications.

Achieving both stretchability and excellent transparency of superhydrophobic surfaces simultaneously is a major challenge. The researchers utilized three acrylic monomers 1H,1H,2H,2H-heptadecafluorodecyl acrylate, methyl methacrylate, 3-(trimethoxysilyl) propyl methacrylate to polymerize flexible, transparent, low surface energy random copolymers (PHMK) as the coating. The coating has excellent transparency (90.2 %) and the coated elastic cotton fabric exhibits superhydrophobicity (WCA = 160°) even at the tensile strain of 0–300 %. The water droplets on the surface can bounce repeatedly in a stretched state.
