Abstract

A method of preparing an antimicrobial coating comprises coating a surface with an aqueous mixture of 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride, 3-chloropropyltrimethoxysilane, and triethanolamine and then coating the surface with an aqueous titanyl sol-gel solution comprising an aqueous mixture of peroxotitanium acid and peroxo-modified anatase sol overtop of the silane to form the antimicrobial coating. The antimicrobial coating exhibits residual antimicrobial efficacy againstandafter water rinsing or after abrasion. The use of 3-chloropropyltrimethoxysilane was found to improve storage stability of the quaternary silane composition and the durability of the antimicrobial coating.
