Abstract:
:Multicolored superhydrophobic coating with high durability has been receiving tremendous attention in decorative applications. Herein, a facile method to fabricate multicolored superhydrophobic coating with excellent robustness has been developed by using cellulose and chitosan. The multicolored coatings can be obtained through single dyeing or mixed dyeing based on three primary dyes. The coating can be applied on hard substrates (e.g. glass, aluminum sheet) and soft substrates (e.g. cotton fabric) by diverse methods including spraying, dip-coating and painting. The colorful coating firmly adheres to the substrates due to the multiple interactions (siloxane covalent bonds and hydrogen bonds). The colorful coating exhibits water-repellant behaviors and can withstand sandpaper abrasion, tape-peeling cycles, water impact, salt spray test and UV environments. Furthermore, the multicolored coating can be used as a new type of pigment for painting on different substrates and is expected to have a huge potential application in technological design or decoration.
