Preparation of New Polymer Nanocomposites and Analysis of Their Superhydrophobic Properties

Abstract

Abstract As an important branch of the superhydrophobic research field, polymer/nano composite superhydrophobic materials have broad application prospects in anticorrosion, self-cleaning and oil-water separation. In this paper, a polymer-based nanocomposite superhydrophobic coating was prepared by a simple method, and its microscopic morphology, wettability and other related properties were characterized and analyzed. The SiO2/PS and SiO2/PVC superhydrophobic nanocomposite coatings were prepared by spin coating. The method is simple, easy to implement, low in cost, and does not require special equipment and harsh conditions. The addition of hydrophobic nano-silica reduces the surface energy of the coating while increasing the surface roughness, without the use of low surface energy substances. The coating exhibits excellent acid and alkali corrosion resistance, and is suitable for a variety of substrates. It can be used as an anticorrosive coating for metal protection and has a good application prospect.
