Fabrication of Colorful Wear-resistant Superhydrophobic Coatings Based on Chemical Modified Halloysite

Abstract Most superhydrophobic coatings have poor mechanical stability and lack color diversity, which severely restricts their practical application. A hybrid superhydrophobic coating was prepared by spraying commercial epoxy resin (EP) and halloysite nanotubes (HNTs) modified by cationic dyes and organosilane. Apart from robust superhydrophobicity (CA>165°, SA
