Structure and Property Characterization of Polyurethane/Graphite Conductive Composites

Two Polyurethane/graphite conductive composites were prepared from natural graphite powder and graphite oxide,respectively.EDS and SEM revealed that the graphite oxide possessed a larger aspect ratio and was more compatible with polyurethane matrix than natural graphite powder.As a result,the composites based on graphite oxide gave rise to higher mechanical and conductive properties.
