Description

technical field

[0001] The invention belongs to the field of polymer composite materials, and in particular relates to a highly thermally conductive graphene-coated inorganic filler composite resin glue material and a preparation method thereof. Background technique

[0002] Graphene is a two-dimensional crystal that is exfoliated from graphite and composed of carbon atoms with only one layer of atomic thickness. This endows graphene with unique thermal properties. It has been reported in the literature that the in-plane thermal conductivity of single-layer graphene has reached the range of 4800-5300 W / mk measured by confocal micro-Raman spectroscopy at room temperature. As a new type of nanomaterial with the thinnest, strongest, and strongest electrical and thermal conductivity found so far, graphene is called "black gold". Therefore, graphene is used to enhance the electrical and thermal conductivity of polymers.
