Abstract

Multifunctional cotton fabric was prepared by coating AgBr–TiO2/OV-POSS nanocomposites using the spray coating method. The increase in surface roughness and high adhesion between the coating and the cotton textile were attributed to the presence of AgBr–TiO2 nanoparticles and the superimposed crosslinking agent octavinyl polyhedral oligomeric silsesquioxane (OV-POSS). Incorporation of the coated layers resulted in an increase in hydrophobicity and a decrease in the surface energy of the cotton fabric. The analytical results showed that the highest water contact angle (WCA) of the cotton fabric coated with AgBr–TiO2(5%)/OV-POSS (0.09%) was 150.8 ± 1.2°. The as-prepared samples exhibited excellent mechanical durability and chemical resistance with up to 30 washes, good UV protection and self-cleaning properties. In addition, the AgBr–TiO2/OV-POSS coated fabrics showed high efficiency in oil/water separation and methylene blue degradation under UV-A irradiation. The antibacterial activity of AgBr–TiO2(5%)/OV-POSS (0.09%) cotton fabrics was tested with K. pneumoniae and S. aureus and showed excellent antibacterial efficacy of > 99%.
