Recently, copper matrix composites reinforced with graphene or graphene-like carbon nanosheets (GNS) have attracted great attention due to their excellent properties. However, the fabrication technologies of the composites are generally complex and expensive; it is necessary to develop facile and cheap synthesis methods for industrial applications of the composites with high performance. Here, we present a very simple method to fabricate GNS reinforced copper composites: commercial Cu powders with oleic acid coating are directly fabricated into GNS/Cu composites by spark plasma sintering. This work provides a facile method with low cost and high efficiency for the preparation of GNS reinforced metal matrix composites with high performance, which opens a new window for the large-scale production of graphene based composites.
最近，由于其优异的性能，石墨烯或类石墨烯纳米片（GNS）增强铜基复合材料引起了极大的关注。然而，这些复合材料的制造技术通常较为复杂且昂贵；因此，有必要开发出简便且廉价的合成方法，以实现具有高性能的复合材料的工业化应用。在这里，我们提出了一种非常简单的方法来制备 GNS 增强铜复合材料：用油酸包覆的商用 Cu 粉末通过火花等离子烧结直接制成 GNS/Cu 复合材料。这项工作为制备具有高性能的 GNS 增强金属基复合材料提供了一种简便、低成本和高效率的方法，为基于石墨烯的复合材料的大规模生产开辟了新的途径。
