Preparation and properties of a strong and durable composite superhydrophobic coating

Abstract

In this paper, from the perspective of improving the durability of superhydrophobic coatings, a strong and durable superhydrophobic coating was prepared by a simple spray method. The coating has good chemical stability and mechanical durability. After soaking in aqueous solution with pH value of 1 and 14 for 30 hours and 24 hours respectively, the contact angle is 139.8 ° and 143.5 °respectively. After 90 times of abrasion, the contact angle is still 148 ° and the coating shows excellent self-cleaning and antifouling properties.
