Description:
Surface coarse structure is one of key factors affecting the superhydrophobicity, yet it’s not very clear that what kind of structure is the best for hydrophobicity. Herein in order to study the effect of surface coarse structure, eight kinds of spherical SiO 2 (20 nm, 60 nm, 200 nm, 500 nm, 1 μm, 2 μm, 5 μm and 10 μm) were taken as raw material respectively to explore the effect of particle size on the hydrophobic performance. SiO 2 was deposited on the glass substrate layer by layer using the electrostatic assembly method based on the reaction of amino and epoxy groups. The sample’s structure and properties were characterized respectively by scanning electron microscopy and contact angle measuring instrument. The relationship between SiO 2 particle size and surface hydrophobicity was explored and the superhydrophobic stability were tested. The results show that the surface of SiO 2 film layers are stacked together and arranged tightly, a...
