Abstract

The invention provides a graphene conductive printing ink composite material. The graphene conductive printing ink composite material mainly comprises, by ratio (according to the mass percents), 1-40wt% of graphene, 10-60wt% of resin-based bonding materials, 10-30wt% of auxiliaries and the like. Graphene conductive printing ink can be prepared according to an experiment method on a large scale. The graphene conductive printing ink composite material has the advantages that the conductive printing ink prepared by the aid of the experiment method is high in electric conductivity and good in toughness, compression molding performance and impact resistance; the shortcomings of environmental pollution and high cost of the traditional conductive printing ink can be overcome, and large-scale commercial production can be expected.

Description

technical field [0001] The invention relates to a conductive ink, in particular to a graphene conductive ink composite material and a preparation method of the conductive ink. Background technique [0002] Graphene is a two-dimensional crystal that is exfoliated from graphite material and composed of carbon atoms with only one layer of atomic thickness. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester, UK, successfully separated graphene from graphite and confirmed that it can exist alone. Bell Prize in Physics. Graphene is both the thinnest material and the strongest, with a breaking strength 200 times stronger than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. The most potential application of graphene at present is to become a substitute for silicon, to manufacture ultra-miniature transistors, and to...
