Abstract

Abstract: Super-hydrophobic nanocoatings are having enormous applications in various fields. In this paper, an attempt was made to prepare the adhesive transparent superhydrophobic coating for optical applications. Nano-silica based coatings were prepared by using tetraethoxyorthosilicate (TEOS) as a silica precursor. Hexamethyldisilazane (HMDS) and Polystyrene were used to make coatings superhydrophobic, transparent, and durable. To evaluate the coating properties, contact angle, and transparency were observed. A tape test was performed to determine coating stability. It was found that the HMDS is responsible for hydrophobicity and Poly-styrene is for adhesion. Poly-Styrene based coatings were more stable compared to only HMDS based coatings.
