Abstract

A GRAPHENE OXIDE (GO) REINFORCED COPPER (CU) MATRIX NANOCOMPOSITE, WAS SYNTHESIZED BY SINTERING UNDER HYDROGEN ATMOSPHERE AND CHARACTERIZED USING SCANNING ELECTRON MICROSCOPY (SEM), VICKERS MICROHARDNESS, DENSIFICATION AND ELECTRICAL CONDUCTIVITY TESTS. NANOCOMPOSITE PROCESS WAS PERFORMED BY MIXING ELECTROCHEMICAL CU POWDER WITH GO AQUEOUS SOLUTION. THE FINAL CONCENTRATION OF GO IN THE NANOCOMPOSITE WAS 0.3 WT%. SINTERING WAS PERFORMED UNDER H2 GAS ATMOSPHERE. THROUGH SEM, IT WAS POSSIBLE OBSERVE THE HOMOGENEOUS DISPERSION OF GRAPHENE SHEETS BETWEEN CU PARTICLES, WITHOUT AGLOMERATION. THE FINAL RESULTS DISCLOSED SIMILAR DENSIFICATIONS AND THE SAME HIGHER ELECTRICAL CONDUCTIVITY VALUES OF THE NANOCOMPOSITE IN COMPARISON TO PURE CU. THE MICROHARDNESS VALUES WERE SLIGHTLY CHANGED WITH THE H2 TREATMENT.
