Recently, many efforts have been dedicated to achieve lightweight, stretchable, and flexible heat device. Here, the Polyester Cleanroom Wiper coated with poly(pyrrole) as flexible material showing electrothermal properties are reported. Poly(pyrrole) particles are synthesized on the cloth via a simple in situ polymerization method with different Py/FeCl3 concentration ratios. A highly conductive cloth with surface resistance of 23 Ω/sq can be produced by changing the Py/FeCl3 concentration. The flexible composites showed sensitive electrothermal performance, and a steady-state temperature of 89.1°C could be reached at 6 V. In addition, temperature, voltage, and time-dependent temperature results showed that the heating performance was strongly dependent on the resistance and external voltage. Herein, as-prepared composites were further analyzed as ultra-fast responding electrothermal heaters, indicating their great potential in application value as wearable electronic textiles.

聚吡咯涂覆在涤纶无尘布上作为加热装置的制备

最近，许多努力致力于实现轻质、可拉伸和灵活的热装置。在这里，报告了涂有聚（吡咯）作为显示电热性能的柔性材料的聚酯洁净室擦拭布。聚（吡咯）颗粒通过简单的原位聚合方法在布上合成，具有不同的 Py/FeCl3 浓度比。通过改变 Py/FeCl3 浓度可以生产出表面电阻为 23 Ω/sq 的高导电布。柔性复合材料显示出灵敏的电热性能，在 6 V 时可达到 89.1°C 的稳态温度。此外，温度、电压和温度随时间变化的结果表明，加热性能强烈依赖于电阻和外部电压。在此处，
