Özet
Herein, we report a single step and a one pot by using spin coating method for the preparation of optically transparent, superhydrophilic, antifogging composite surface. The wettability performance and also antifogging properties of these surfaces were investigated depending on silica particles content in composite solution. It was also examined the effects of production technique changes on wettability and antifogging characteristics of these surfaces having 20% wt silica particles content. The apparent water contact angle of transparent surfaces were found to vary between 65 degrees and 4 degrees depending on the silica content, polymer type and production technique. Superhydropilic surface (WCA = 4 degrees) displayed a good antifogging performance and light permeability behavior. It was also observed that antifogging behavior kept showing when water contact angle is lower than 15 degrees. However, antifogging properties disappeared when water contact angle is higher than 25 degrees. These results were showed that one step-one pot reaction have a better results than two step reactions depending on silica particles adding time.
