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.
铝（Al）及其合金因其优异的物理性能而广泛应用于各个领域。尽管人们已经做出了许多努力来制备铝基复合材料，但通常会导致电导率显著下降。在此，通过一种简便的方法成功设计并制备了一种特殊的层状结构Al/石墨烯（Gr）/Al复合材料，该方法是对石墨烯粉末进行超声喷雾并去除氧化铝，随后进行真空热压工艺。所制备的Al/Gr/Al复合材料的电导率显著提高，达到66%IACS，远高于其他报道的铝基复合材料，同时仍保持相似的力学性能。这项工作为开发高导电性铝基复合材料提供了一种新策略，这对实际应用将非常有用且重要。
