Title The preparation of the conductive polymer decorated Buckypaper
Abstract
Supercapacitors known as electrochemical capacitors, have been recognized as a new type of energy storage devices that fill the gap between batteries and conventional capacitors. Supercapacitors have been rapidly developed in recent years due to their high specific capacitance, high power density, a short time of charge, the charge-discharge efficiency and long cycle life. The performance of supercapacitors is largely depended on the electrode materials. As a result, the electrode materials attract a lot of attention around scientist all over the world.Our study is focused on the preparation of the conductive polymer decorated buckypaper and their effect and mechanism. Firstly , we prepareed the buckypapers by vacuum filtration method and then a pulsed potentio amperometric polymerization was performed in an aqueous to coat polypyrrole(PPy) onto the carbon nanotubes network of buckypaper.The morphology of the buckypaper was obsered with Scan Electron Microscope(SEM),Opitical microscopy characterization was carried out on a Microscope. And the electrochemical measurement,including cyclic voltammetry(CV) and galvanostatic charge/discharge tese were performanced on an Autolab.the result demonsrates that conductive polymer decorated buckypaper can be an excellent candidate electrode materials for high performance supercapacitors.
