The invention discloses a graphene and nano-silver composite material and a preparation method, and belongs to the technical field of graphene and nano-silver composite materials. By controlling the type and quantity of oxygen-containing functional groups in graphene oxide, combined with Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization technology, oxygen-containing segments can be oriented and controllably grafted on the surface or edge of graphene. (Nano-silver nucleation and growth site), by designing and regulating different oxygen-containing functional groups and their grafting sites and numbers, and controlling the active position and number of nano-silver nucleation and growth, the loading method and loading amount of nano-silver can be precisely regulated , load morphology, provide an ideal experimental carrier for studying the relationship between conductive ink filler structure and conductivity; provide high-performance filler for the research and development of high-performance conductive ink. |
