Abstract
Superamphiphobic coatings with excellent repellency to low surface tension liquids and multiple self-healing abilities are very useful for practical applications, but remain challenging to realize. Previous papers on self-healing superamphiphobic coatings have demonstrated limited liquid repellency with single self-healing ability against either physical or chemical damage. Herein, we describe a superamphiphobic fabric that has remarkable multi-self-healing ability against both physical and chemical damages. The superamphiphobicity was prepared by a two-step surface coating technique. Fabric after coating treatment showed exceptional liquid-repellency to low surface tension liquids including ethanol. The fabric coating was also durable to withstand 200 cycles of laundries and 5000 cycles of Martindale abrasion without apparently changing the superamphiphobicity. This highly robust, superamphiphobic fabric may find applications for the development of "smart" functional textiles for various applications.
