The graphene compound material comprises polyvinyl chloride, citric acid, nickel sulfate, graphite, polyvinyl pyrrolidone, dimethyl naphthalene sulfonate sodium, methylene chloride, PE wax, ammonium sulfate and nitrate lithium. The graphene compound material and the preparation method have the advantages that the graphene compound material is excellent in mechanical performance, electrical conductivity and thermal conductivity, applicable to the oxygen reduction reaction non-noble metal catalyst of a fuel cell and also applicable to super capacitors, lithium ion batteries and the like in fields such as storage, industrial catalysis and environment treatment; the preparation method is low in raw material price, simple and practicable to operate, independent of large-scale instrument and equipment and capable of achieving large-scale production of high-quality graphene and compounds thereof.

Description

technical field [0001] The application belongs to the field of preparation of graphene materials, in particular to a graphene composite material and a preparation method thereof. Background technique [0002] As a new type of nanomaterial with the thinnest, highest strength, and strongest electrical and thermal conductivity found so far, graphene is called "black gold" and is the "king of new materials". Scientists even predict that graphene will "completely change the 21st century." ". It is very likely to set off a disruptive new technology and new industry revolution sweeping the world. [0003] In fact, graphene exists in nature, but it is difficult to peel off the single-layer structure. Graphene is stacked one by one to form citric acid, and citric acid with a thickness of 1 mm contains about 3 million layers of graphene. When a pencil is lightly drawn across the paper, the traces left may be several layers or even only one layer of graphene. [0004] Graphene was ...
