Polyurethane has been known as a polymeric material that has high mechanical strength and has been widely used as adhesive, film, and etc. But it has poor thermal or electical conductivity. So if we want applicate conductive material, we must try something to enhance electrical, thermal properties. expanded graphite has simmilar structure compare with graphene, so it has good electrical and thermal properties. In this work, we synthesis various ratio PU-Carbon material composite and check several properties. Morporlogy was monitered by SEM. Thermal property was measyred by thermal conductivity analysis. Electrical proprety measured by 4-probe resistance analysis. Mechanical property measured by UTM. |
