采用原位聚合法在针织物表面涂覆聚吡咯, 制备具有良好导电性能的柔性导电针织物.采用红外摄像仪采集不同电压下聚吡咯涂层针织物的表面温度图像.结果显示, 聚吡咯涂层针织物平衡温度随着施加电压的升高而升高, 聚吡咯涂层针织物的表面温度与织物的功率密度成正比.对聚吡咯涂层针织物温度随时间的变化曲线进行拟合, 拟合相关系数均大于0.9783.在10次循环加热测试中最高温度和稳态平均温度的变化率分别为7.04％和3.4％.柔性加热针织物在积极发热保暖服装领域具有非常广阔的应用前景.“,”The polypyrrole knitting fabrics were obtained by in-situ polymerization.The surface temperature of fabrics was measured by infrared camera.The result showed that the fabrics temperature rised with increasing the voltage.The fabrics temperature was proportional to the power density of fabrics.The curve of temperature changing with time was fitted, and the correlation coefficients were larger than 0.9783.The change rate of highest temperature and the stable average temperature was 7.04％ and 3.4％ respectively.Flexible heating knitted fabrics had very broad application prospect in the field of positive warm clothing.
