Abstract

Transparent mesoporous silica coatings were achieved by conventional sol-gel process. The obtained coatings display permanent supra-amphiphilicity, transparent appearance and good wetting property with very fast spread rate. Incorporation of functional materials such as cyrstalline titania nanoparticles into the coatings was also carried out without affecting the transparency and supra-amphiphilicity.
