Abstract

Electrospun nanofibers with highly efficient photothermal/electrothermal performance are extremely popular because of their great potential in wearable heaters. However, the lack of necessary wearable properties such as high mechanical strength and quick response of electrospun micro/nanofibers seriously affects their practical application. In this work, a technical route combining electrospinning and surface modification technology is proposed. The 3-triethoxysilylpropylamine-polyacrylonitrile@ copper sulfide (K-PAN@CuS) composite fabric was achieved by modifying the original electrospinning PAN fiber and subsequently loading CuS nanoparticles. The results show that the break strength of the K-PAN@CuS fabric was increased by 10 times compared to that of the original PAN@CuS fabric. Furthermore, the saturated temperature of the K-PAN@CuS fabric heater could reach 116 °C within 15 s at a relatively low voltage of 3 V and 120.3 °C within 10 s under an infrared therapy lamp (100 W). In addition, due to its excellent conductivity, such a unique structural design enables the fiber to be closely attached to the human skin and helps to monitor human movements. This K-PAN@CuS fabric shows great potential in wearable heaters, hyperthermia, all-weather thermal management, and in vitro physical therapy.

制备具有优异光热/电热性能的可穿戴 K-PAN@CuS 复合织物

具有高效光热/电热性能的电纺纳米纤维因其在可穿戴加热器方面的巨大潜力而备受青睐。然而，电纺微/纳米纤维缺乏必要的可穿戴性能，如高机械强度和快速反应，这严重影响了其实际应用。本研究提出了一种结合电纺丝和表面改性技术的技术路线。通过对原电纺 PAN 纤维进行改性，并在其中添加 CuS 纳米粒子，得到了 3-三乙氧基硅丙胺-聚丙烯腈@硫化铜（K-PAN@CuS）复合织物。结果表明，K-PAN@CuS 织物的断裂强度比原来的 PAN@CuS 织物提高了 10 倍。此外，K-PAN@CuS 织物加热器的饱和温度在相对较低的 3 V 电压下可在 15 秒内达到 116 ℃，在红外线治疗灯（100 W）下可在 10 秒内达到 120.3 ℃。此外，由于具有出色的导电性，这种独特的结构设计使纤维能够紧贴人体皮肤，有助于监测人体运动。这种 K-PAN@CuS 织物在可穿戴加热器、热疗、全天候热管理和体外物理治疗方面显示出巨大的潜力。
