Low defect multi-layer graphene was synthesized through electrochemical intercalation of graphite electrode in ammonium sulfate aqueous solution, followed by microwave heating and ultrasonication. The combination of ethanol as antifoaming agent, alternating current and end-face electrolysis was highly effective for achieving a high yield (>75%) production of low defect graphene. The synthesized graphene was then used to produce graphene/Al composites using stir casting method. The graphene/Al composites with a graphene loading of 0.3% exhibited approximately 40% higher tensile strength (142.2 MPa) and much lower coefficient of thermal expansion (19.8 x 10-6/K) compared to pure Al (104.0 MPa, 22.7 x 10-6/K).
Low defect multi-layer graphene has been synthesized by electrochemical intercalation of graphite electrode in ammonium sulfate aqueous solution, followed by microwave heating and subsequent ultrasonication. Combination of addition of ethanol as antifoaming agent, alternating current and end-face electrolysis was very effective for high yield production (>75%) of low defect graphene. We applied as-synthesized graphene for graphene/Al composites using stir casting method. Graphene/Al composites with a graphene loading of 0.3% have approximately 40% higher tensile strength (142.2 MPa) and much lower coefficient of thermal expansion (19.8 x 10-6/K) as compared with pure Al (104.0 MPa, 22.7 x 10-6/K).
