RELEASE CONTROL OF ANTIMICROBIAL MATERIAL S COATED WITH HYDROLYZED TETRAETHOXYSILANE

Anti-microbial materials were synthesized with thiosulfatosilver compl ex on silica gel. Release ratio of the effective component from the ma terials was improved with coating on the surface with hydrolyzed tetra ethoxysilane (TEOS). It was observed by EPMA (Electron probe micro ana lyzer) that the effective component from the materials was leached out around the materials through the resin. It was also confirmed that th e coating was effective for the improvement of release ratio with incr easing amount of TEOS used.
