Abstract

A xerogel film exhibiting antifouling properties. The films are made using long-chain alkyltrialkoxysilanes, short-chain alkyltrialkoxysilanes, aminoalkyltrialkoxysilanes, alkylaminoalkyltrialkoxysilanes, dialkylaminoalkyltrialkoxysilanes, and perfluororalkyltrialkoxysilanes as sol-gel precursors. The films can be used as coatings on surfaces to reduce or eliminate fouling resulting from attachment and/or growth of biofoulants such as algae, diatoms, bacteria, barnacles, and biofilms.
