PAN/PEG/CNT/cotton composite yarn (PPCCY) was fabricated by impregnating PEG2000–10000 into CNT/cotton yarn (CCY) and coating electrospun PAN around its surface. The effects of PEG type on the morphology, structure, electrical resistance and phase change behavior of the produced composite yarns were studied thoroughly by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermal gravimetric(TG), electrical resistance tester and infrared thermal images. The experimental results indicated that the resulting compound yarn consisted of conductive yarn within which the spacing between cotton fibers was fulfilled by PEG, rendering phase transition enthalpy from 126–150 Jg−1. The composite yarn exhibited adjustable temperature and thermal storage and electrical conductivity abilities. The composite yarn demonstrated good responsive properties to external electrical and thermal stimuli and had reversible heat conversion and storage, which shows a promise for applications in electrical wearable fabrics.

具有相变和导电功能的新型复合棉纱

PAN / PEG / CNT /棉复合纱(PPCCY)是通过将PEG2000-10000浸渍到CNT /棉纱(CCY)中并在其表面涂覆电纺PAN制成的。通过扫描电子显微镜(SEM),傅立叶变换红外光谱(FTIR),差示扫描量热法(DSC),热重分析法,深入研究了PEG类型对所生产复合纱线的形态,结构,电阻和相变行为的影响。 (TG),电阻测试仪和红外热像仪。实验结果表明,所得复合纱线由导电纱线组成,其中棉纤维之间的间距通过PEG满足,相变焓从126–150 Jg -1。该复合纱线表现出可调节的温度和热存储以及导电能力。该复合纱线对外部电刺激和热刺激表现出良好的响应特性,并具有可逆的热转化和储热能力,这为在电可穿戴织物中应用提供了希望。
