ABSTRACT A simple, accurate and rapid construction method of superhydrophobic fabric coating was provided. Firstly, a homogeneous solution was obtained by dissolving a certain amount of silicone resin and polymethyl methacrylate (PMMA) in N,N-Dimethylformamide (DMF). Then, a nanocrystals solution system was made by adding ethanol to the homogeneous solution to induce the crystallization of PMMA. Finally, a superhydrophobic fabric coating was constructed by casting the nanocrystals solution on the surface of cotton cloth. “Tyndall effect”, scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), water contact angle (CA) and self-cleaning test were adopted to characterize the solution system and the coating. Results showed that the nanocrystals solution had obvious “Tyndall effect”. The water CA of the coating reached 153.1°, displaying obvious superhydrophobicity. Besides, concave-convex micro-nano structures were produced on the surface of the fabric coating and endowed it with good self-cleaning capacity.
