Abstract

The present investigation deals with the fabrication of a novel flexible and highly conductive PPy electrode. This was made by festooning PPy nanoparticles on carbon cloth (CC) by using chemical liquid process. The developed porous PPy@CC composite have good flexibility with low weight (1.1 mg) and high electrical conductivity (89 Ωcm). Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction spectroscopy (XRD) confirmed the formation of PPy on carbon cloth. Scanning electron micrographs (SEM) reveals that the PPy nanoparticles are encapsulated in carbon cloth. The fabricated carbon cloth has been used for solid-state symmetrical supercapacitors (SC) and low-cost material for electrode in potential energy storage devices. These film electrodes showed much superior electrochemical performance i.e. high stability under different current density, encouraging energy density, lower internal resistivity and higher specific capacitance. Synthesized flexible PPy@CC composite electrodes have brilliant applications in various kinds of electrochemical energy storage devices.

摘要

本研究涉及一种新型柔性高导电聚吡咯(PPy)电极的制备。它是通过化学液相法将PPy纳米颗粒装饰在碳布(CC)上制成的。所制备的多孔PPy@CC复合材料具有良好的柔韧性、低重量(1.1毫克)和高电导率(89Ω·cm)。傅里叶变换红外光谱(FTIR)和X射线衍射光谱(XRD)证实了碳布上PPy的形成。扫描电子显微镜图像(SEM)显示PPy纳米颗粒被包裹在碳布中。所制备的碳布已用于固态对称超级电容器(SC)以及潜在储能设备中低成本的电极材料。这些薄膜电极表现出优异的电化学性能,即在不同电流密度下具有高稳定性、令人鼓舞的能量密度、较低的内阻和较高的比电容。合成的柔性PPy@CC复合电极在各种电化学储能设备中具有出色的应用。
