Abstract：
Aluminum (Al) and its alloys are widely used in various fields due to their excellent physical properties. Although many efforts have been made to fabricate an Al-based composite, they usually results in a significant decrease in electrical conductivity. Herein, a special layer-structured Al/graphene (Gr)/Al composite was successfully designed and fabricated through a facile method using the ultrasonic spraying of graphene powder with alumina removal and a subsequent vacuum hot-pressing process. The as-obtained Al/Gr/Al composite presents a significantly enhanced electrical conductivity of 66% IACS, which is much higher than that of other reported Al-based composites, while it still maintains similar mechanical properties. This work provides a new strategy for the development of highly conductive Al-based composites, which would be very useful and important for practical applications.
摘要：
背景技术铝(Al)及其合金由于其优异的物理性能而广泛应用于各个领域。尽管已经做出了许多努力来制造铝基复合材料，它们通常导致电导率的显著降低。在这里，一种特殊的层状结构的Al/石墨烯（Gr）/Al复合材料是通过一种简单的方法成功地设计和制造的，该方法使用超声波喷涂石墨烯粉末并去除氧化铝以及随后的真空热压工艺。获得的Al/Gr/Al复合材料的电导率显着提高了66％IACS，远高于其他报道的铝基复合材料，虽然它仍然保持类似的机械性能。这项工作为开发高导电铝基复合材料提供了一种新的策略，这对实际应用非常有用和重要。
