导电双疏涤纶织物制备与性能研究

目的制备具有良好导电性能的超疏水疏油纺织品。方法首先利用化学镀方法在涤纶织物表面镀铜,构筑微米-亚微米粗糙结构,然后利用全氟辛基三甲氧基硅烷(PFTMS)通过化学气相沉积方法在镀铜织物表面覆盖一层低表面能基团,制备导电超疏水疏油织物。采用电子扫描电镜(SEM)、能量色散X射线光谱仪(EDXS)、接触角测试仪和方阻测试仪对其表面形貌、表面元素分布、疏水疏油性、导电性能进行研究。结果 PFTMS修饰的镀Cu织物导电性能优异,方阻为230 mΩ左右,织物抗紫外线指数达到50+;织物与水滴接触角达152.0°,与十六烷油滴接触角达120.7°。结论将化学镀和化学气相沉积法相结合,在涤纶纤维表面化学镀铜并用PFTMS进行低表面能物质修饰,可以成功制备具有导电功能的超疏水疏油纺织品。

Preparation and Properties of Conductive,Superhydrophobic and Oleophobic Polyester Fabrics

ABSTRACT:Objective To prepare superhydrophobic and oleophobic textile fabrics with good conductive property. Methods The surface of polyester fabric was first coated with copper using the chemical copper-plating method to build a micron-submicron struc-ture. Then the superhydrophobic and oleophobic conductive fabrics were fabricated through chemical vapor deposition of 1H,1H, 2H,2H-perfluorooctyltrimethoxysilane (PFTMS) to generate a layer of low surface energy group on the surface of the Cu-planted polyester fabrics. The properties of amphiphobic polyester fabrics including surface morphology, element distribution, amphipho-bicity and electrical conductivity were investigated with scanning electron microscope ( SEM) , energy dispersive X-ray spectroscopy ( EDXS) , contact angle tester and square resistance tester. Results It showed that the PFTMS-Cu-modified polyester fabrics had outstanding conductive capability, the sheet resistance was about 230 mΩ, and the resistance to UV performance was up to 50+. The contact angles of the modified polyester fabrics with water and n-hexadecane were 152. 0° and 120. 7°, respectively. Conclu-sion Superhydrophobic and oleophobic fabrics with good conductive property could be successfully fabricated using PFTMS by chemical copper-plating and chemical vapor deposition method.
