摘　　要：为了增强聚吡咯(Ppy)加热织物的安全性、环保性,提升Ppy与棉织物附着牢固性,将纳米陶瓷颗粒(NCP)与水性聚氨酯(WPU)按一定比例进行掺杂,采用刮涂法在Ppy织物表面均匀成膜,制备出WPU/NCP/Ppy织物。通过控制单一变量法优选出原位聚合法制备Ppy织物的工艺参数,在此基础上对制备的WPU/NCP/Ppy织物电热性能、表面形貌、老化性能、功耗等进行了测试与表征。结果表明:制备Ppy织物的最优工艺为吡咯单体浓度0.4 mol/L、反应时间120 min、反应环境温度0℃~5℃;制备的WPU/NCP/Ppy织物红外发射率高达0.86,导热系数为0.2875 W/(m·K),在表面绝缘和防止老化方面优于PPy织物,在较低温度的室外环境下功耗较少。认为:WPU/NCP涂层对Ppy织物的稳定性、安全性具有一定的提升作用,保温效果更好。In order to enhance the safety and environmental protection of polypyrrole(Ppy)heating fabric and improve the adhesion between Ppy and cotton fabric,nano-ceramic particles(NCP)and water-borne polyurethane(WPU)were doped in a certain proportion.WPU/NCP/Ppy fabric was prepared by scraping and coating on the surface of Ppy fabric.The technological parameters to prepare Ppy fabric by in-situ polymerization were optimized by controlling single variable method.On this basis,the electrothermal property,surface morphology,aging property and power consumption of WPU/NCP/Ppy fabric were tested and characterized.The results showed that the optimum conditions for Ppy fabric preparation were pyrrole monomer concentration 0.4 mol/L,reaction time 120 min and reaction environment temperature 0℃~5℃.The infrared emissivity ability of prepared WPU/NCP/Ppy fabric was 0.86,and the thermal conductivity was 0.2875 W/(m·K),which was superior to PPy fabrics in the surface insulation and anti-aging.The power dissipation at lower temperature outside was lower.It is considered that WPU/NCP coating can improve the stability and safety of Ppy fabric,and the insulation effect is better.
