NOVELTY - The reduced graphene oxide/polypyrrole/filter paper composite flexible electrode material preparing method involves cutting a filter paper into a desired shape, immersing the filter paper in an aqueous solution of ferric chloride for 30 minutes and taking out and draining in a refrigerator. The immersed filter paper is immersed in an isopropanol solution having a concentration of 1-2 vol.% pyrrole monomer for 24 hours to obtain product. The product is taken out and drained, washed with deionized water and vacuum-dried at room temperature for 24 hours to obtain dried product. The dried product is immersed in a graphene dispersion having a concentration of 0.16-2.4 mg/L for 1-3 hours and an equal volume of 0.1-0.2 mol/L is added to the mixture of ascorbic acid solution and stirred for 12 hours, followed by taking out and draining the product, washing with deionized water and vacuum-drying at room temperature for 24 hours to obtain the finished product. USE - Method for preparing reduced graphene oxide/polypyrrole/filter paper composite flexible electrode material. ADVANTAGE - The method enables preparing reduced graphene oxide/polypyrrole/filter paper composite flexible electrode material with excellent energy storage potential and high specific capacitance, in flexible and cost effective manner. DETAILED DESCRIPTION - The reduced graphene oxide/polypyrrole/filter paper composite flexible electrode material preparing method involves cutting a filter paper into a desired shape, immersing the cutted filter paper in an aqueous solution of ferric chloride having a molar concentration of 0.1-0.5 mol/L for 30 minutes and taking out and draining in a refrigerator for 4 degrees C. The immersed filter paper is immersed in an isopropanol solution having a concentration of 1-2 vol.% pyrrole monomer for 24 hours to obtain product. The product is taken out and drained, washed with deionized water and vacuum-dried at room temperature for 24 hours to obtain dried product. The dried product is immersed in a graphene dispersion having a concentration of 0.16-2.4 mg/L for 1-3 hours and an equal volume of 0.1-0.2 mol/L is added to the mixture of ascorbic acid solution and stirred for 12 hours, followed by taking out and draining the product, washing with deionized water and vacuum-drying at room temperature for 24 hours to obtain the finished product. An INDEPENDENT CLAIM is also included for a reduced graphene oxide/polypyrrole/filter paper composite flexible electrode material prepared by the method.
