Abstract | Preparation of superamphiphobic coatings with low sliding angles (SAs) for liquids of low surface tension is challenging. Here, a simple and sustainable approach for preparation of superamphiphobic coatings with low SAs from attapulgite/carbon (APT/C) composites is reported. The coatings are prepared by hydrolytic condensation of 1H,1H,2H,2H-perfluorodecyltriethoxysilane and tetraethoxysilane with the APT/C composites followed by spray-coating onto substrates. The APT/C composites are prepared by pyrolysis of spent bleaching earth containing APT. The influences of pyrolysis temperature of spent bleaching earth and the APT/C concentration on superamphiphobicity and surface morphology of the coatings are studied. Carbon nanoparticles are formed on the APT nanorods in the pyrolysis process. The APT/C nanorods are wrapped and linked together by a layer of fluorinated polysiloxane (fluoroPOS). The coatings exhibit excellent superamphiphobicity with high contact angles (CAs) and low SAs even for n-decane (CAn-decane = 154.2°, SAn-decane = 11.3°). This is because the new three-tier micro-/nano-/nanostructure is constructed by the combination of APT nanorods, carbon nanoparticles, and fluoroPOS. Also, |
