摘要：

为制备导电率高且柔性的多功能热电织物,采用低温原位聚合法制备了对甲苯磺酸离子掺杂聚(3,4-乙烯二氧噻吩)(PEDOT∶Tos)包覆聚丙烯纤维的核壳结构热电织物。借助扫描电子显微镜、傅里叶变换红外光谱仪、红外热成像仪对热电织物的结构和性能进行表征与分析。结果表明:热电织物兼具织物优异柔韧性和PEODT∶Tos 良好的导电性,电导率可达2.1 S/cm;当在热电织物两端施加10 V的电压时,其表面温度提高近20 ℃,具有良好电热性能,可将电能有效地转化为热能;由热电织物所构建的热电转化装置处在温差为20 ℃的温度梯度场中时,可持续输出0.3 mV的电压。

Abstract:

In order to prepare high-conductivity, flexible, and multifunctional thermoelectric fabrics, a low-temperature in-situ interfacial polymerization method was proposed to fabricate core-shell thermoelectric textile with p-toluenesulfonic acid ion-doped poly(3,4-ethylenedioxythiophene) (PEDOT∶Tos) coated with polypropylene(PP) fibers. The structure and performance of thermoelectric fabrics were characterized and analyzed by scanning electron microscope, Fourier transform infrared spectrometer, and infrared thermal imager. The results show that the prepared thermoelectric fabrics have excellent flexibility as a textile materials, and good conductivity due to PEDOT∶Tos with conductivity reaching 2.1 S/cm. When a voltage of 10V is applied to both ends of a thermoelectric fabric, the surface temperature increases by about 20 ℃, indicating good electric heating performance and effective conversion of electric energy into heat energy. When the thermoelectric conversion device constructed using the thermoelectric fabric is placed in a temperature gradient field with a temperature difference of 20 ℃, it can continuously output a voltage of 0.3 mV.

Key words: thermoelectric fabric, poly(3,4-ethylenedioxythiophene), low-temperature interfacial polymerization, p-toluenesulfonic acid ion, thermoelectric conversion device, polypropylene nonwoven fabric
