Physical Properties of 3D Interconnected Graphite Networks - Aerographite

Abstract

This report is an exploration of the electrical properties of Aerographite, an ultralight cellular material consisting of an interconnected graphite structure layered over a zinc oxide scaffold, which is removed to leave a compressible, flexible, but conductive structure. The structure showed high conductivity (up to 10 S/m) and a piezoresistive behaviour and low capacitance and frequency independent impedence under AC testing, referring to good shielding properties. Capacitance was also measured while immersed in sodium fluouride. Additionally, correlation with morphology was accomplished. The results show Aerographite has promise as a strain sensor, cyclically stable battery electrode, fuel cell catalyst, and more.
