Abstract
SynopsisHeat-resistant and optical coating films were synthesized with fluorinated silsesquioxane having surface reforming ability based on the double-decker shaped structure. Surface, optical, and thermal properties were evaluated by contact angle measurement, UV-vis spectroscopy, and thermal gravimetric analysis, respectively. In this study, we confirmed the following points; (1)Surface free energy of the films can be controlled by addition of a small amount of fluorinated silsesquioxane.(2)The coating films were superior in transparency and have little absorption in near ultraviolet region, so that the film had stability against ultraviolet irradiation. (3)Decomposition temperature of these films was higher than 300℃. (4)The bulk properties were not influenced by addition of fluorinated silsesquioxane. Through this study, the coating films composed of fluorinated silsesquioxane derivatives are expected to give a novel hybrid films superior in transparency and heat resistance.
