Abstract

Glassy polymeric carbon (GPC) has a unique graphite micro-fibril structure that attributes singular properties to the material. The addition of nanoparticles in the GPC matrix to improve its properties has been the focus of recent studies for spacecraft coating applications. We report the effects of Al2O3 nanoparticles dispersed in GPC on the electrical properties. The fabrication process to produce homogenous samples and the electrical measurements are fully described. In addition, the chemical structure characterization was evaluated using Raman spectroscopy.
