摘要:

铜基材料的强度与电导率互相矛盾,其已成为高端铜材研发的关键技术瓶颈。石墨烯因其独特的结构和性质,可作为铜基材料理想的增强体,可显著提高材料的力学性能。为此,针对国内外相关研究现状,详细阐述了当前石墨烯铜基复合材料的制备方法,即粉末冶金法、分子水平混合法、化学气相沉积法以及电化学沉积法等。同时,对石墨烯在铜基复合材料中的强化机理做出解释,并提出相应的计算公式进行量化处理,以便于将实验值与理论值进行对比。最后,对未来石墨烯铜基复合材料的性能改进(包括高质量单层石墨烯制备)和石墨烯-铜取向结晶一致进行了展望。

Abstract:

The strength and electrical conductivity of copper-based materials contradict each other,which has become a key technical bottleneck in the development of high-end copper materials.Due to its unique structure and properties,graphene can be used as an ideal reinforcement for copper-matrix materials,which can significantly improve their mechanical properties.Therefore,in view of relevant research status at home and abroad,the current preparation methods of graphene-copper matrix composites were described in detail,including powder metallurgy,molecular-level mixing,chemical vapor deposition and electrochemical deposition.At the same time,the strengthening mechanism of graphene in copper-based composites was explained,and the corresponding calculation formula was put forward for quantitative processing,which was convenient to compare the experimental value with the theoretical value.Finally,the future performance improvement of graphene-copper matrix composites(including high-quality monolayer graphene preparation) and consistent graphene-copper orientation crystallization were prospected.

Key words: grapheme/copper based matrix composites, strengthening mechanism, high-speed rail contact wire
