一种导热多孔石墨烯-环氧树脂复合材料的制备方法
摘要：
本发明公开了一种导热多孔石墨烯‑环氧树脂复合材料的制备方法，本发明将石墨切片氧化后，震荡至形成稳定悬浮液，之后利用1,2,4‑三氨基苯二盐酸盐及其他材料进行处理，高温处理后形成多孔氧化石墨烯，之后通过和氧化铝、碳纳米管混合，熔融加热处理，喷涂硅烷偶联剂，挤出研磨粉碎均匀，与熔融的环氧树脂中混合固化既得多孔石墨烯‑环氧树脂复合材料。本发明制备了多孔石墨烯与氧化铝、碳纳米管结合后，与环氧树脂复合，制备的复合树脂韧性和强度均较好，具有良好的导热性。
摘要（英）：

The invention discloses a preparation method of a heat conductive porous graphene/epoxy resin composite material. After oxidizing graphite chips, the graphite chips oscillate to form a stable suspension, 1,2,4-triaminobenzene dihydrochloride salt and other materials are used for treatment, high temperature treatment is performed to form porous graphene oxide, mixing with alumina and carbon nanotubes is performed, melted heating treatment is performed, a silane coupling agent is sprated, uniform extrusion grinding pulverization is performed, and the porous graphene-epoxy composite material is obtained by mixing and curing in the melted epoxy. The porous graphene is prepared and combined with alumina and carbon nanotubes, and is composited with epoxy resin, and the prepared composite resin has good toughness and strength, and has good heat conductivity.
