Abstract

The use of thermoelectric fabrics for powering wearable devices is expected to become widespread soon. A thermoelectric fabric was prepared by coating nanocomposite of polyaniline/graphene nanosheets (PANI/GNS) on a fabric. Four samples of the fabric containing different wt% of GNS (0.5, 2.5, 5, and 10) were prepared. To characterize the samples, Fourier transform infrared (FTIR) spectra, attenuated total reflectance-Fourier transform infrared (AT-FTIR) spectra, field-emission scanning electron microscopy (FE-SEM), electrical conductivity and Seebeck coefficient measurements were used. The electrical conductivity increased from 0.0188 to 0.277 S cm⁻¹ (from 0.5 to 10 wt% of the GNS in PANI/GNS nanocomposite). The maximum coefficient of Seebeck was 18 µV K⁻¹ with 2.5 wt% GNS at 338 °C. The power factor improvement was from 2.047 to 3.084 μW m⁻¹ K⁻² (0.5–2.5 wt% GNS).

超声浸涂法制备聚苯胺/石墨烯包覆的耐磨热电织物

摘要

使用热电织物为可穿戴设备提供动力有望很快普及。通过在织物上涂覆聚苯胺/石墨烯纳米片（PANI / GNS）的纳米复合材料来制备热电织物。制备了四个包含不同wt％的GNS（0.5、2.5、5和10）的织物样品。为了表征样品，使用了傅里叶变换红外（FTIR）光谱，衰减全反射-傅里叶变换红外（AT-FTIR）光谱，场发射扫描电子显微镜（FE-SEM），电导率和塞贝克系数测量。电导率从0.0188 S cm ^-1增加到0.277 S cm ^-1（在PANI / GNS纳米复合材料中，从GNS的0.5到10 wt％）。塞贝克的最大系数为18 µV K ^-1在338°C下含有2.5 wt％的GNS。功率因数提高了2.047至3.084μWm ^-1  K ^-2（0.5-2.5 wt％GNS）。
