摘要
本文以固化后的有机硅聚合物为低表面能物质,大理石石粉纳米颗粒为无机填料,喷涂在不同基材的表面后,制备了具有超疏水性能的PTFMS-TEOS杂化涂层。考察了大理石石粉与有机硅聚合物复合的比例及温度对涂层疏水性的影响。用接触角测量仪和扫描电子显微镜分别对超疏水表面进行了结构分析和形貌表征。结果显示,当大理石石粉与PTFMS-TEOS质量比1:3时杂化涂层表面具有较好的超疏水功能,静态接触角可达153?,这主要是涂层表面含有低表面能氟原子及具有纳米粗糙结构共同作用的结果。
A super hydrophobic PTFMS-TEOS hybrid coating was prepared after solidified silicone polymer as low surface energy material, marble powder and nano particle as inorganic filler and sprayed on different substrates. The effect of the proportion and temperature of marble stone powder and organosilicon polymer on the hydrophobicity of the coating was investigated. The surface of the superhydrophobic surface was analyzed and characterized by the contact angle measuring instrument and the scanning electron microscope respectively. The results show that when the marble powder and PTFMS-TEOS mass ratio is 1:3, the surface of the hybrid coating has super hydrophobic function, and the static contact angle can reach 153 degrees, which is mainly due to the joint action of low surface energy fluorine atoms and nano rough structure on the coating surface.
