One-Pot Synthesis of Conducting Graphene Polymer Composites and Its Strain Sensing Application (Preprint).

摘要

In-situ reduction of graphite oxide in polymer powder has been implemented using focused solar electromagnetic radiation. Graphene has proved that it can act as alternative filler in nanocomposites due to its high electronic transport properties and its use in advanced polymer composites for EMI shielding applications. With an applied load, strain measured and corresponding change in resistance of the reduced graphite oxide-polymer composites has been observed. The morphological, structural, electrical, thermal, and electromechanical characteristics of the reduced graphene-PVDF were studied. A gauge factor was obtained demonstrating a promising application as a strain sensor in structural health monitoring.
