Abstract

The structure and properties of a copper–n-layer graphene composite obtained under high-pressure and high-temperature (HPHT) conditions were studied depending on the method of mixing the mixture components using a Pulverisette 6 classic line ball mill, an EXAKT three-roll mill, and manual mixing. It was established that, regardless of the method of mixing the components, the addition of n-layer graphene increased the thermal conductivity of the composite compared to pure copper. The highest thermal conductivity (559 W/(m K)) was exhibited by a composite sintered from a mixture obtained by manual mixing due to the uniform distribution of the components in the mixture and to minimization of the plastic deformation of copper particles during the mixing.

取决于组分混合方法的铜-n-层石墨烯复合材料的结构和性能

摘要

研究了在高压和高温（HPHT）条件下获得的铜-n层石墨烯复合材料的结构和性能，这取决于使用Pulverisette 6 classic在线球磨机（例如EXAKT三塔轧机和手动混合。已经确定，与混合组分的方法无关，与纯铜相比，添加n层石墨烯均可提高复合材料的导热性。通过由手动混合获得的混合物烧结的复合材料，由于混合物中组分的均匀分布以及混合过程中铜颗粒的塑性变形最小化，从而表现出最高的导热系数（559 W /（m K）） 。
