The invention discloses graphene composite dyeing line slurry, and particularly relates to the technical field of graphene materials.

Background

Graphene is a two-dimensional carbon nanomaterial consisting of carbon atoms in sp2 hybridized orbitals to form a hexagonal honeycomb lattice. The graphene has excellent optical, electrical and mechanical properties, has important application prospects in the aspects of materials science, micro-nano processing, energy, biomedicine, drug delivery and the like, and is considered to be a revolutionary material in the future. The physicists andrelim and consanguin norworth schloff, manchester university, uk, successfully separated graphene from graphite by micromechanical exfoliation, thus collectively awarding the 2010 nobel prize for physics. Common powder production methods of graphene are a mechanical stripping method, an oxidation-reduction method and a SiC epitaxial growth method, and a thin film production method is a Chemical Vapor Deposition (CVD) method.

The heating wire inside the heating cloth is a graphene heating wire formed by single graphene, and the existing dyeing wire slurry of the graphene heating wire is large in size of slurry particles, low in stability of dispersion liquid and low in stability of polymers, so that the conductivity of other finished products made of the slurry is poor.
