摘要

以硅藻土和TiO2为微纳米结构的构筑物,以聚二甲基硅氧烷为低表面能改性剂,采用喷涂法在多种基底表面制备超疏水涂层材料。该涂层具有优异的超疏水性能,水静态接触角高达161°,表面自清洁性能优异,且耐热温度可高达350℃。该超疏水涂层材料在纺织品自清洁、医用防水及工业防腐等领域具有一定的应用前景。

Abstract

In this study,superhydrophobic coating materials were prepared on various substrate surfaces by spraying method with diatomite earth and titanium dioxide as the micro-nano structures and PDMS as the low surface energy modifier.The coating had excellent superhydrophobic properties with a water static contact angle up to 161°,excellent surface self-cleaning performance,and heat resistance up to 350℃.After 150 times of mechanical strength test experiment,the static contact angle of the coating was still as high as 151°.It had certain application prospects in the fields of textile self-cleaning,medical waterproofing and industrial anticorrosion.
