Graphene composite powder material and preparation method thereof

一种石墨烯复合粉体材料及其制备方法

Abstract

The invention provides a preparation method of a graphene composite powder material. The preparation method comprises the following steps: (a) providing a first solution, and dispersing a graphene material in the first solution to obtain a graphene pre-dispersion solution, wherein the first solution contains a dispersing agent; (b) providing a second solution which contains a grinding aid; (c) grinding the graphene pre-dispersion solution and metal powder in the second solution to obtain a grinding dispersion solution; and (d) carrying out vacuum freeze drying on the grinding dispersion solution to obtain the graphene composite powder material. The invention further provides the graphene composite powder material.
本发明提供一种石墨烯复合粉体材料的制备方法,其包括以下步骤:(a)提供一第一溶液,将石墨烯材料分散于所述第一溶液得到石墨烯预分散液,其中所述第一溶液含有分散剂;(b)提供一第二溶液,所述第二溶液含有砂磨助剂;(c)将石墨烯预分散液、金属粉体于所述第二溶液中进行砂磨,得到砂磨分散液;以及(d)将所述砂磨分散液进行真空冷冻干燥,得到石墨烯复合粉体材料。本发明还提供一种石墨烯复合粉体材料。
