主 题：superhydrophobic coating cellulose hybrid nanomaterials anti-icing
摘 要：Herein,we proposed and demonstrated a facile and scalable strategy to fabricate multifunctional self-similar superhydrophobic ***,a hydrophobic cationic cellulose derivative containing imidazolium cation was synthesized by a controllable *** could effectively disperse one-dimensional(1D)multi-walled carbon nanotubes(MWCNT),because the imidazolium cations formed cation–πinteractions with ***,the synergy effect of the cationic cellulose derivative and MWCNT dispersed two-dimensional(2D)reduced graphene oxide(rGO)to obtain a three-components ***,via a simple spaying process,a superhydrophobic coating with self-similar micro-nano structures spontaneously formed from inside to outside,owing to the various nanostructures with different shapes and sizes in the dispersion and the adhesive effect of the cellulose *** superhydrophobic coating was easy to scale,exhibited superior stability owing to the renewal micro-nano *** retained the superhydrophobicity even if it was treated by rubbing for 1500 ***,it had outstanding photo-thermal and Joule-heating performance,because of the strong solar absorption and high electrical conductivity of MWCNT and *** provided both passive anti-icing and active deicing ***,it could achieve all-weather anti-icing for wind power generators under sunlight and low voltage *** facile preparation method and multifunctional renewable superhydrophobic coating hold great application prospects.
