超疏水-高疏油SiC膜的制备及性能
Preparation and properties of superhydrophobic-highly oleophobic SiC membrane
摘要
Abstract
A process was developed to prepare a superhydrophobic-highly oleophobic surface on SiC membrane based on SiO2 particle blending spraying and immersion method.By spraying SiO2 particles of different sizes,a micro-nano dual rough structure with amphiphobic capability was created on the surface of the SiC membrane.Then,perfluorodecyltrimethoxysilane was grafted onto the SiC membrane surface through immersion,successfully achieving a SiC membrane with superhydrophobic-highly oleophobic characteristics and excellent self-cleaning performance.The effects of different parameters,such as fluorine content and surface roughness,on surface wettability were analyzed.The modified superhydrophobic-highly oleophobic SiC membrane exhibited the static water contact angle of 152.6°and the static contact angle of n-hexadecane of 146.3°.The sliding angles were measured to be 5.2°and 10.2°,respectively.These properties could be attributed to the micro-nano structure on the SiC membrane surface and the low surface energy material,which reduced the adhesion between the surface and other substances.The superhydrophobic-highly oleophobic SiC membrane also exhibited stable amphiphobicity in strong acid and alkali solutions.This research provided a simple process for constructing superhydrophobic-highly oleophobic surfaces with excellent acid-base resistance on inorganic membranes.关键词
