mPolypyrrole / cotton composite electrode material for supercapacitor was prepared by chemicaloxidation method using cotton woven fabric and cotton spunlace non-woven fabric as flexible substrate. Theelectrical properties of electrode material samples were studied. The results showed that the electrode materialsamples had good electrical properties and capacitor characteristics. The specific capacity of polypyrrole / cottonfabric and polypyrrole / cotton nonwoven electrode material sample is 346 F / g and 282 F / g respectively at acurrent density of 0. 1 A/ g. A flexible solid state supercapacitor was assembled with the PVA-H3PO4 gelelectrolyte respectively with two samples of the electrode material. The same electrochemical performance testwas carried out on the sample of the capacitor. When the current density was 1 mA·cm - 2, the surfacecapacitance of the solid state supercapacitor assembled with the polypyrrole / cotton woven fabric electrodematerials and polypyrrole / cotton nonwoven fabric electrode materials was 0. 64 F / cm2（152. 2 F / g） and 0. 44F / cm2（115. 7 F / g）.
