In situ growth of oriented polyaniline nanorod array on pencil core and its electrochemical energy storage
摘要
Abstract
Conductive polymers could be used as electrode materials for supercapacitors and had great potential applications in small energy storage devices.This article used waste short pencils as raw materials to peel off the pencil core(PC)as a supporting substrate for supercapacitor electrode materials.Then,the ordered polyaniline(PANI)nanorod arrays were in situ grown on the surface of the pencil core by dilute solution method to form PANI@PC electrode.As a carbon material with good conductivity,pencil core could quickly achieve electron transfer and export when it combined with PANI with ordered micro/nano structure.Even at high scanning rates or current densities,the inner active material could still participate in electrode reactions,thereby improving the utilization of electrode materials to enhance the electrochemical properties of composite materials.The experiment showed that the specific capacitance of PANI@PC electrode could reach 470 F/g at a current density of 1 A/g,and the loss of specific capacitance is only 25.5%when the current density increases to 10 A/g.Further analysis of the charge storage mechanism of PANI@PC electrode shows that the electrode reaction is controlled by fast kinetics,that is,the double layer capacitance and Faradaic pseudocapacitance on the surface of PANI@PC electrode contribute,which is conducive to achieving good rate performance of electrode materials.This study could provide guidance for the preparation of composite conductive polymers/nanomaterials for supercapacitors.关键词
