摘要
将碳纳米管(CNT)和聚吡咯纳米线(NPPy)通过超声附着到纺织纤维——聚酯纤维上,制备了CNT/NPPy/聚酯纤维复合柔性电极和全固态纤维状柔性超级电容器。通过扫描电子显微镜、傅立叶红外光谱和拉曼光谱对复合电极的形貌和结构进行表征,通过循环伏安法和充放电测试等研究了超级电容器的电化学性能。充放电测试结果表明所制备的纤维状柔性超级电容器具有较高的比容量,其表面积比容量为6.34×10–3 F/cm^2,长度比电容为0.36×10–3F/cm(充放电电流密度:1.7×10–6A/cm^2)。且其循环800圈后,电容只下降33%,当弯曲500次后,该超级电容器的电容量保持率为76%,显示出了良好的柔性和弯曲稳定性。该柔性纤维状超级电容器的制备方法步骤简单,成本低廉,所制备的柔性纤维状超级电容器可纺织到衣服面料或其他纺织品中,在便携式和可穿戴电子产品中具有潜在应用前景。
Flexible electrodes, carbon nanotube （CNT）/polypyrrole nanowire （NPPy）/polyester composite fibers, were firstly prepared by adsorption of CNT and NPPy on polyester fibers, and then all-solid flexible wire-shaped supercapacitor devices using the composite fibers as electrode material were fabricated. The morphology and structure of the flexible electrodes were characterized by scanning electron microscopy, infrared spectroscopy and Raman spectroscopy. Charge and discharge tests show that the surface area specific capacitances is 6.34×10-3F/cm2 and the length specific capacitances is 0.36×10-3F/cm at 1.7×10-6 A/cm2, with 33% capacitance loss after 800 cycles. After being bend for 500 times, the supercapacitor can retain more than 76% of initial capacitance, showing good flexibility and stability. The preparation method of CNT/NPPy/polyester supercapacitor is simple, low-cost, and eco-friendly. The all-solid flexible wire-shaped supercapacitor can be woven into clothes, bags, or other fabrics, and shows potential application in portable and wearable electronic equipment.
