Biomimetic Super Anti-Wetting Coatings from Natural Materials: Superamphiphobic Coatings Based on Nanoclays.

ABSTRACT: Superamphiphobic coatings (SAPCs) that resist wetting of water and low-surface-tension liquids have generated widespread attention in academia, but are very challenging to invent. Liquid adhesion, low stability, complicated and expensive preparation methods are the typical characteristics of SAPCs, which seriously hinder real-world applications of SAPCs. Here, we report a comprehensive study about preparation of SAPCs from abundant nanoclays with fibrous, plate-like and porous microstructures. The SAPCs are prepared simply by hydrolytic condensation of silanes in the presence of nanoclays, followed by spray-coating the as-formed suspensions onto substrates. The SAPCs feature high superamphiphobicity for various liquids down to a surface tension of 23.8 mN m^-1 (n-decane), and hig
