摘要：

为制备一种功能性的复合涤纶织物,首先利用氧等离子体技术改性处理增加涤纶纤维的润湿性,然后采用溶液法制备银纳米线(AgNWs)并分散到无水乙醇中,通过浸渍-烘干工艺整理到涤纶(PET)织物表面,并采用热压工艺处理AgNWs/PET织物以提高AgNWs的吸附牢度。探讨不同银纳米线溶液质量浓度对AgNWs/PET性能的影响。结果表明:随着银纳米线质量浓度由1 mg/mL增加到4 mg/mL,AgNWs/PET织物的方块电阻由25.38 Ω/?减小至2.51 Ω/?,但耐洗性能较差;经等离子体改性处理后,AgNWs/PET织物的导电性能明显优于未处理织物;先经过氧等离子体处理再采用热压工艺处理,不仅能提高织物的导电性,且经过50次洗涤后,AgNWs/PET织物的方块电阻由0.67 Ω/?增加至0.83 Ω/?,仅增加了24.89%,耐洗性有较大改善。

Abstract:

In order to prepare a functional composite polyester fabric, oxygen plasma-modified treatment and hot pressing processing were firstly adopted to increase the wettability of the polyester(PET), then the silver nanowires(AgNWs) were dispersed into anhydrous ethanol and the PET fabric was treated with the AgNWs ethanol colloid by a dip-drying process. The AgNWs/PET fabrics were treated by hot pressing process to improve the adsorption fastness of AgNWs. The influence of different concentrations of the colloid on the properties of AgNWs/PET was investigated. With the concentration of the colloid increases from 1 mg/mL to 4 mg/mL, the square resistance of the AgNWs/PET reduces from 25.38 Ω/? to 2.51 Ω/?, but the washing resistance is poor. The electrical conductivity of the AgNWs/ PET which was modified by oxygen plasma is improved after hot-pressing. In addition, after 50 times of washing, the square resistance is increased only by 24.89% , from 0.67 Ω/? to 0.83Ω/?, but the washing resistance is greatly improved.

Key words: silver nanowires, polyester fabric, plasma treatment technology, hot pressing process, electrical conductivity, washing resistance
