Development of Silica Thin Film as a Self-Cleaning Surface on Various Materials

Abstract

Materials with superhydrophobic surfaces have received great attention fom scientists recently. One of the materials that have this property is silica thin film. Silica thin film has been widely studied due to its high hydrophobicity and ability to be applied in various materials. Superhydrophobic silica thin film has a water contact angle of more than 150; consequently, it is suitable for applications as an anti-fogging, anti-reflective and self-cleaning material which is in great demand by the industry to develop. The development of superhydrophobic materials with self-cleaning capabilities has several advantages, such as reducing maintenance costs, increasing durability, preventing snow or ice adhesion, and protecting materials from the effects of environmental pollution. Superhydrophobic silica thin films have been developed in various materials that are on glass surfaces, wood surfaces, stainless-steel, and cotton fabric coatings. This chapter focuses on discussing the latest developments of superhydrophobic thin film silica applied on various materials.
