由于具备高强、高模、高导热等优异的性能,石墨烯被认为是先进复合材料中理想的增强体。然而,由于缺乏有效的制备手段,对于石墨烯增强金属基复合材料的研究十分有限,且石墨烯的增强效果远未达到预期的水平。针对此关键问题,郭强教授课题组基于仿生复合的学术思想,采用改进的粉末冶金工艺,在石墨烯-纯铝模型体系中制备具有纳米叠层结构的石墨烯增强 Due to its excellent properties of high strength, high modulus and high thermal conductivity, graphene is considered as an ideal reinforcement in advanced composite materials. However, due to the lack of effective preparation methods, the research on graphene reinforced metal matrix composites is very limited, and the enhancement effect of graphene is far from the expected level. In response to this key issue, based on the bionic composite academic idea, Prof. Guo Qiang’s group enhanced the graphene with nano-stack structure in the graphene-pure aluminum model system by the improved powder metallurgy
