Fabrication of Biomimetic Superhydrophobic Coating with a Micro‐Nano‐Binary Structure

Abstract

Abstract Summary: A superhydrophobic coating was facilely fabricated in one step by casting bisphenol A polycarbonate (PC) solution under moisture. Vapor‐induced phase separation occurred during the solidifying process and a rough surface with a micro‐nano‐binary structure (MNBS) similar to the microstructure shown on lotus leaf was formed.
