The invention discloses a method for preparing Cu/graphene/carbonized polydopamine composite powder by in-situ reduction and vacuum sintering methods. The preparation method comprises the following steps: using a Tris buffer solution as a dispersion medium, adding Cu powder and graphene oxide, adding dopamine, violently stirring for a certain time, and centrifugally precipitating to obtain a complex of Cu/graphene/polydopamine. The complex is subjected to vacuum sintering to obtain a target product. The preparation method has the advantages of simple and convenient synthetic process, green and environment-friendly reaction and the like. 本发明公开了种通过原位还原以及真空烧结的方法制备Cu/石墨烯/碳化聚多巴胺复合粉体的方法。该制备方法以Tris缓冲溶液作为分散介质，加入Cu粉和氧化石墨烯，加入多巴胺，剧烈搅拌定时间，经离心沉淀得到Cu/石墨烯/聚多巴胺的复合物。将复合物经真空烧结得到目的产物。本制备方法具有合成工艺简便、反应绿色环保等优点。
