| Description |
Anatase TiO(2) and Ag nanoparticles (NPs) codoped SiO(2) films were prepared by the sol-gel method. Proportionate amounts of 3-(glycidoxypropyl)trimethoxysilane (GLYMO), tetraethylorthosilicate (TEOS) and 3-(methacryloxypropyl)trimethoxysilane (MEMO) derived inorganic organic silica sol, commercially available dispersed anatase TiO(2) NPs, and AgNO(3) were used to prepare the sols. The films were prepared on ZrO(2) (cubic) precoated soda-lime glass substrates by a single-dipping technique and heat-treated at 450 degrees C in air and H(2)/Ar atmosphere to obtain hard, relatively porous, and transparent coatings of thickness >600 nm. The ZrO(2) barrier layer was previously applied on soda-lime glass to restrict the diffusion of Ag into the substrate. The Ag-TiO(2) NPs incorporated SiO(2) films were intense yellow in color and found to be fairly stable at ambient condition for several days under fluorescent light. These films show a considerable growth inhibition on contact with the gram negative bacteria E. coli.
