摘　　要：采用原位镀银法制备了具有优良导电性的纤维素纤维织物,探究了AgNO_3浓度、葡萄糖用量、温度等因素对织物的镀银量和导电性的影响。通过表面方阻测试、拉伸强度、接触角、耐洗涤性等分析了镀银棉织物导电性能、力学性能、疏水性和镀层结合情况。所制备的镀银棉织物的表面方阻低至75mΩ/,扫描电镜显示纤维表面均匀覆盖银纳米粒子,将纤维素纤维的亲水性表面转变为疏水性表面,同时显著提高了棉织物的热稳定性和机械性能,导电织物具有较好的耐洗涤性,有望应用于可穿戴智能织物的电极材料。Cellulose fiber fabric with excellent electrical conductivity was prepared by in situ silver plating method.The effects of AgNO3 concentration,glucose content and temperature on the silver plating and conductivity of the fabric were investigated.The electrical conductivity,mechanical properties,hydrophobicity and coating combination of silver-plated cotton fabrics were analyzed by means of surface resistance test,tensile strength,contact angle and washing resistance.The surface resistance of the silver-plated cotton fabric is as low as75 mΩ/□.The scanning electron microscope images show that the surface of the fiber is evenly covered with silver nanoparticles.After plated with silver,the hydrophilic surface of cellulose fibers is transformed into hydrophobic surfaces and the thermal stability and mechanical properties of cotton fabric are improved significantly.Conductive fabric has good washing resistance and is expected to be used as electrode material for wearable intelligent fabric.
