Abstract In this study, we demonstrated simultaneously enhanced mechanical properties and electrical conductivity of pure aluminum (Al) by incorporating graphene as the reinforcement. The graphene/Al nanocomposite was fabricated by friction stir processing (FSP) combined with hot extrusion. It was found that graphene was homogeneously dispersed into Al matrix and directly bonded graphene/Al interfaces were formed, which were the structure basis for the simultaneously improved electrical and mechanical properties. This study provides new strategy for fabricating high-strength and highly conductive graphene/Al nanocomposites.

以石墨烯为增强材料同时提高铝的机械性能和导电性

摘要 在这项研究中，我们证明了通过将石墨烯作为增强材料同时增强了纯铝 (Al) 的机械性能和导电性。石墨烯/铝纳米复合材料是通过搅拌摩擦加工（FSP）结合热挤压制备的。结果表明，石墨烯均匀分散在铝基体中并形成直接键合的石墨烯/铝界面，这是同时提高电学和机械性能的结构基础。该研究为制造高强度和高导电石墨烯/铝纳米复合材料提供了新的策略。
