Scalable Preparation of Superamphiphobic Coatings with Ultralow Sliding Angles and High Liquid Impact Resistance
Source abstract
Abstract
In spite of great progress, preparation of superamphiphobic coatings with excellent static and dynamic superamphiphobicity remains challenging. Here, we report superamphiphobic coatings with ultralow sliding angles and high liquid impact resistance. The coatings were prepared by spray-coating the polysiloxane/silica stock suspensions, synthesized by hydrolytic condensation of silanes with silica nanoparticles. The superamphiphobicity relies on microstructure of the coatings, controllable by the diameter of silica nanoparticles. The coatings feature excellent static and dynamic superamphiphobicity for various liquids with surface tension as low as 23.8 mN m–1. Furthermore, we achieved large-scale preparation of the coatings, which paved the way for their applications.
