Facile Preparation of Flexible, Optically Transparent Superhydrophobic Surfaces by Conjugated Microporous Polymer

摘要

Creation of optically transparent superhydrophobic surfaces has increased extensive attention in the self-cleaning area. In this work, flexible, optically transparent superhydrophobic surfaces were fabricated by coating the conjugated microporous polymer on poly(dimethylsiloxane) (PDMS) substrate over large areas without using any expensive or complicated techniques. Result shows that the as-treated PDMS films exhibit super water repellence with a water CA of 163°. The surface superhydrophobicity should be contributed to both the strong hydrophobic surface chemical compositions and the micoporous morphological structures of the polymer microgel particles. The as-treated PDMS film also exhibits excellent optical transparency. Our study could not only prove to be a route to superhydrophobic surfaces but also may pave the way for large-scale, commercial production of flexible, optically transparent superhydrophobic surfaces, which is greatly technological significance for large-scale fabrication of self cleaning surfaces, anti-fogging coatings, etc..
