Mechanical strength values up to 17.41 MPa, in-plane electrical conductivity values up to 136.6 S/cm, through-plane electrical resistance of 0.027 Ohm-cm and flexibility (deflection at mid-span) values up to % 4.38 were obtained with epoxy impregnation in expanded graphite foams. The low thickness (similar to 0.5 mm) and density (similar to 1.2 g/cm(3)) values of the prepared composite plates put them one step ahead for mobile applications which require high mass and volumetric power density (W/kg, W/L). On the other hand, corrosion current and contact angle values of these composite plates couldn't achieve desired values.eninfo:eu-repo/semantics/closedAccessConference Object4111869187710.1149/1.36357172-s2.0-84866389466Q4WOS:000309598800179N/A
