| Abstract |
In this study, the characteristics of anti-pollution coatings on glass substrates through annealing treatment were investigated. To investigate the change of properties by coating method and number of annealing treatment, after the anti-pollution coating was performed on the surface of glass substrate in three ways, the annealing treatment was performed by setting three kinds of annealing treatment conditions. The annealing treatment method is a torch using gas, which is advantage in that it can be installed directly on the site in an easy way compared with a annealing treatment process which is generally difficult. The anti-pollution properties, contact angle, transmittance, hardness, and adhesion of films on glass substrate were measured under 9 conditions of combination of coating methods and annealing treatment conditions. It was confirmed that as the number of annealing treatment increases, the anti-pollution property of the film synthesized on glass substrate becomes better. |
