In order to improve the interface wettability as well as the interfacial bonding between graphene and copper matrix, in this work, graphene nanoplates modified with nickel nanoparticles (Ni-GNPs) were synthesized using a one-step method based on spray-drying and chemical vapor deposition. Thereafter, 0.33 wt% Ni-GNPs were introduced into copper matrix composite by the molecular-level mixing method, leading to further enhancement of 90% in yield strength. This is attributed to the presence of Ni-GNPs, which provided high resistance to matrix against deformation. In addition, with the modification of nickel at the interface, the wettability and interfacial bonding between graphene nanoplates and copper matrix were improved, which enhanced the load transfer then. Furthermore, the microstructures and strengthening mechanisms were investigated and discussed meanwhile.

镍纳米粒子修饰的石墨烯纳米板的制备以增强铜基复合材料

为了提高界面润湿性以及石墨烯与铜基体之间的界面键合，在这项工作中，基于喷雾干燥和化学气相的一步法合成了用镍纳米粒子（Ni-GNPs）改性的石墨烯纳米板。沉积。此后，通过分子水平混合法将0.33wt％的Ni-GNPs引入到铜基复合材料中，导致屈服强度进一步提高了90％。这归因于Ni-GNP的存在，其对基质提供了高的抗变形性。此外，通过对界面处的镍进行改性，改善了石墨烯纳米板与铜基体之间的润湿性和界面键合，从而增强了载荷传递。此外，
