Abstract:A superhydrophobic coating with the structure of "concave and convex gully" structure like the foot of water strider was prepared on the surface coated with epoxy/gutta-percha varnish using palygorskite powder as the functional pigment and the mixture of epoxy resin and gutta-percha as the film-forming material. The surface morphology and structure were characterized by means of scanning electron microscope (SEM), infrared spectroscopy (FTIR), X-ray diffraction spectrum (XRD). The water contact angle, water rolling angle, self-cleaning property, wettability, wear resistance and water resistance of C3 coating (mass fraction of palygorskite powder was 25%) were tested. The results showed that the surface of C3 coating had obvious "concave and convex gully" structure, the average static and dynamic water contact angle were 153.1° and 152.6°respectively, and the water rolling angle was 8.8°, which had excellent self-cleaning performance. In addition, the C3 coating also showed excellent wettability resistance to mud slurry, methyl orange solution and methylene blue solution, and all the contact angles were above 150°. The C3 coating had good substrate applicability, and showed super hydrophobic properties on the surface of concrete, fabric, paper and plastic. After 50 times of cyclic polishing of A4 paper with a load of 100 g, the water contact angle was still as high as 151.9°, with good wear resistance. After soaking for 18 and 24 h, the water contact angle of C3 coating were 152.2° and 144.5°, respectively.
