摘要
在过去的几年中,固体表面的超疏水性研究已经在诸多领域中引起人们的关注,包括表面结构,流体动力,以及工程和生物技术等[1,2]。超疏水现象的理论解释主要有杨氏方程,Wenzel方程和Cassie方程。这些理论表明,无论是固体材料的表面能还是表面结构都可以影响液滴在固体表面的接触角。一般情况,获得超疏水表面的方法可以分为两类:(1)构造具有微纳结构的表面,增大表面粗糙度;(2)用低表面能物质修饰粗糙表面,降低材料的表面能。目前,制备具有超疏水性能的粗糙表面的方法有很多,如层层沉积法、浸涂法、平板印刷法、化学气相沉积法、溶胶-凝胶生长法、等离子处理法、一锅法、电化学沉积法等。本文主要采用静电纺丝法制备二氧化硅微球/聚乙烯醇复合纤维,再煅烧除去纤维中的聚乙烯醇,最后经过氟硅烷处理,得到具有超疏水性能的二氧化硅纤维。
State Key Laboratory of Urban Water Resource and Environment, Harbin Institute of Technology, Harbin, 150090, In the past few years, superhydrophobic phenomenon on the surface of the solid has aroused people's attention in many fields, including surface structure, fluid power, as well as engineering and biotechnology[1,2]. Superhydrophobic phenomenon theory includes mainly young's equation, the Wenzel equation and Cassie equation. These theories suggest that the contact angles on the surface are affected by both surface energy and surface structure of the solid materials. Generally, the strategies of achieving superhydrophobic property can be divided into two categories:(1) increasing the surface roughness via constructing micro-nano structure;(2) reducing the surface energy of materials. At present, there are several methods to construct rough surface of materials, such as layer by layer deposition, dip-coating method, plate-printing method, chemical vapor deposition method, sol-gel method, plasma treatment method, and electrochemical deposition method. In this work, a kind of silica-sphere fibers with superhydrophobic property is fabricated via the electrospinning method.
