| Abstract |
| This study was performed to develop an antibacterial film that can be dried at room temperature. A nanosized TiO2 particle-dispersed solution was prepared by the hydrothermal treatment of peroxo-titanic acid at 160℃ for 4h. The binder was synthesized through the hydrolysis and condensation reactions of TEOS (10cc) and GPTS (3.5cc) in the mixture of H2O (30cc) and EtOH (30cc). The synthesized binder was mixed with 0.1 M of TiO2 solution in a volume ratio of binder/TiO2 solution=0.25~0.5. The glass substrate was coated after using the dip coating method, which was then followed by drying for over 2h at room temperature. Although the TiO2 particles did not chemically-bond to the binder, the coating layer strongly adhered to the substrate and displayed good antibacterial properties. |
