1-pyrenecarboxylic acid Functionalization of Graphene: Effect on Capacitive Energy Storage

ORAL

Abstract

We will present a comparison of Electrolytic Double Layer Capacitance (EDLC) performance of membrane electrodes fabricated using pure and 1-pyrenecarboxylic acid (PCA)-functionalized graphene flakes. A significant increase in specific capacitance as well as energy and power density values in PCA graphene electrodes indicates that surface functionalization (that affects the hydrophilicity) of graphene-based materials is crucial for improving capacitive energy storage ability of these materials.
