Preparation of Hydrophilic-Oleophobic Antireflective Coatings with High Transmittance
Keyword(s):
In this study, hydrophilic-oleophobic antireflective coatings with high transmittance were prepared via simplely mixing the base-catalyzed TEOS and acid-catalyzed MTES with different weight ratio. The refractive index of the AR coatings increase continuously from 1.23 to 1.44. When the weight ratio of acid-catalyzed MTES reached 60%, a hydrophilic-oleophobic antireflective coatings with a high transmittance of 99.09% can be obtained. The water contact angle and the oil contact angle of the coating are 113.8o and 74.4o, which can effectively prevent the absorption of water and polar organic molecules from the environment.
