Graphene intercalation compounds with electroactive polymers such as polyaniline have demonstrated promise in supercapacitor device applications as electrode materials. We are currently investigating the morphological and electrochemical properties of Laponite/polyaniline/graphene and graphene oxide powders and films in order to better understand this complex material system. Crystallinity and morphological studies were carried out using powder X-ray diffraction, scanning electron microscopy, atomic force microscopy, and surface area analysis. Distribution and mixing of materials was further investigated with energy dispersive X-ray maps and optical microscopy. Electrical characterization includes cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy. A deeper understanding of material distribution and interfacial interactions and their effects on the electronic-transport capabilities within the bulk composite will facilitate implementation of these materials into devices.
