【Abstract】 The ultra water-repellent surfaces can provide many kinds of excellent properties,which has been widely used.A coating agent was fabricated via blending of modified SiO2 particles with other compounds.An ultra water-repellent surface was obtained by coating on PVC membrane with this coating agent,then baked.This paper discussed the effects of the dosage of several compounds on the surface properties and morphologies.The effects of surface microstructures on water contact angles were researched preliminarily.The results showed that the ultra water-repellent surface was prepared successfuly by using modified SiO2 particles and the optimal coating process conditions were found.The roughness of surface structures had a direct influence on the water contact angles.更多还原
