Hexagonally arrayed structures of colloidal crystals with uniform particle size are good candidates for templates for synthesizing porous nanostructures. Herein, we present the first reported use of three-dimensionally (3D) ordered porous structures to increase the energy storage abilities of conducting polymer based energy storage devices. A robust 3D colloidal crystal template was prepared using a colloidal suspension. Polypyrrole (PPy) was deposited into the interstices between the colloidal spheres by electrochemical infiltration. PPy inverse nanoporous structures were obtained by dissolving the colloidal template in a solvent (99.5% Benzene). The morphologies of nanoporous PPy structures and their electrochemical characteristics were investigated.
