Abstract

The invention discloses graphene electrothermal film slurry, a preparation method thereof and an electrothermal film. The graphene electrothermal film slurry is prepared from the following components in parts by weight: 0.5 to 2 parts of graphene A, 0.1 to 0.5 part of graphene B, 15 to 35 parts of resin, 15 to 45 parts of filler, 0.5 to 2 parts of dispersing agent, 0.1 to 0.5 part of adhesion promoter, 0.1 to 0.5 part of directional stabilizer and 14.25 to 63.65 parts of solvent, wherein the particle size of the graphene A is larger than that of the graphene B; by compounding the graphene A and the graphene B with different particle sizes and the directional stabilizer, the obtained slurry is prepared into the electrothermal film, the heating is more uniform, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of graphene electrothermal film materials, in particular to a graphene electrothermal film slurry, a preparation method thereof, and an electrothermal film. Background technique [0002] Graphene is a sp 2 A new material in which hybridized carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure; graphene has excellent optical, electrical, and mechanical properties, and is widely used in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It has important application prospects and is considered to be a revolutionary material in the future. [0003] Ordinary electric heating film is mainly made of carbon crystal electric heating film. Carbon crystal electric heating film has certain problems in heating uniformity, durability is average, and its service life is usually only 3-5 years. The core reason is still the problem of electric heating...
