Preparation of superhydrophobic surface from raspberry like particles of bifunctional polyssesquioxane

Abstract

AbstractIn this article, we selected MTMS and ETMS as mixed precursors to generate polysiloxane particles on the surface of styrene copolymer microspheres, forming raspberry‐like particles. The best experimental formula was obtained by orthogonal test. When the ratio of MTMS and ETMS was 3:1, the hydrophobic properties of composite particles reached the best, with a water contact angle (WCA) of 163° and a WSA of 3°. The hydrophobic models of raspberry particles were established. And the influence of gas–liquid contact components, surface roughness and precursor ratio on hydrophobic properties was clarified by theoretical calculation, Fourier transform infrared and X‐ray diffraction analysis. The prepared superhydrophobic surface shows great application potential in self‐cleaning, antifouling and other fields.
