Release Control of Anti-microbial Materials Coated with Hydrolyzed Tetraethoxysilane

Abstract

Anti-microbial materials were synthesized with thiosulfatosilver complex on silica gel. Release ratio of the effective component from the materials was improved with coating on the surface with hydrolyzed tetraethoxysilane (TEOS). It was observed by EPMA (Electron probe micro analyzer) that the effective component from the materials was leached out around the materials through the resin. It was also confirmed that the coating was effective for the improvement of release ratio with increasing amount of TEOS used.
