摘要
电热织物随着智能穿戴纺织品的兴起逐渐成为重要的组成部分。为了提高导电织物舒适性和实现自主电热功能,通过浸渍法使银纳米线均匀分布在双罗纹棉针织物的表面,制备了具有自主电热转换功能的导电针织物。结果表明,此导电针织物最低电阻达到219 mΩ,具有优异的导电能力;在5 Hz的频率和10 N的外力作用下,导电针织物具有4.3 V的开路电压和2.1 nA的短路电流;导电针织物在1.5 V的电压下最高温度保持在64.2℃;导电针织物的电热转换具有优异的可重复性,在20次的重复测试中最高温度均能保持在60℃左右。制备的具有低电阻和优异电热转换性能的导电棉针织物在医用防护、智能保温和储能等领域具有潜在的应用价值。
With the rise of smart wearable textiles,electric heating fabrics have gradually become an important part.In order to improve the comfort of conductive fabric and realize the self-heating function,the conductive knitted fabric with self-heating conversion function was prepared by impregnating silver nanowires uniformly on the surface of double-rib cotton knitwear.The results show that the lowest resistance of the knitted fabric reaches 219 mΩ,which has excellent electrical conductivity.The knitted fabric has an open circuit voltage of 4.2 V and a short circuit current of 1.6 nA at a frequency of 5 Hz and an external force of 10 N.The maximum temperature of the fabric is kept at 64.2℃at 1.5 V voltage.The electrothermal conversion of knitted fabric has excellent repeatability,and the maximum temperature can be maintained at about 60℃in 20 repeated tests.The prepared conductive cotton knitted fabric with low resistance and excellent electriothermal conversion performance has potential application value in medical protection,intelligent insulation,and energy storage.
