摘要
采用聚多巴胺(PDA)对纯棉织物(CF)进行改性预处理,通过简单的浸渍-干燥法将银纳米线(AgNWs)固定到织物表面,成功制备AgNWs/PDA/CF复合导电织物。分析了聚多巴胺改性织物的表面形貌,对比了AgNWs/CF与AgNWs/PDA/CF的导电性能与力学服役性能。结果表明,改性预处理成功在织物表面形成PDA涂层,有效提高了织物对AgNWs的吸附能力,复合导电织物方阻低至9Ω/sq。同时,使用弱酸性洗涤剂在家用洗衣机中洗涤1 h后,AgNWs/PDA/CF的电阻变化率约为150%(AgNWs/CF在同样条件下的电阻变化率为6000%)。此外,AgNWs/PDA/CF具有优异的力学稳定性,能够抵抗折叠、剥离等机械破坏。
Polydopamine(PDA)was used to modify and pretreat pure cotton fabric(CF),and silver nanowires(AgNWs)were fixed on the fabric surface by a simple impregnation-drying method to successfully prepare AgNWs/PDA/CF composite conductive fabric.The surface morphology of the polydopamine modified fabric was analyzed,and the conductive properties and mechanical service performance of AgNWs/CF and AgNWs/PDA/CF were compared.The results show that the modifying pretreatment successfully formed a PDA coating layer on the fabric surface,which effectively improved the adsorption capacity of the fabric to AgNWs,and the square resistance of the composite conductive fabric was as low as 9Ω/sq.Meanwhile,after 1 h of simulated washing in a household washing machine with a weakly acidic detergent,the resistance change rate of AgNWs/PDA/CF was about 150%(the resistance change rate of 6000%for AgNWs/CF under the same conditions).In addition,AgNWs/PDA/CF has excellent mechanical stability and can resist mechanical damages such as folding and peeling.
