Abstract

The invention relates to the technical field of graphene, in particular to a graphene heating film prepared through water transfer printing and a preparation method of the graphene heating film. According to the invention, graphene micro-powder is embedded into the surface of a light-cured resin aliphatic modified epoxy acrylate composite film and is immobilized, and graphene is allowed to form a film, so a good heating effect and heating uniformity are ensured; and the graphene film is stretched, dispersed and thinned through water flow, and a uniform graphene thin layer is formed on the surface of a polyimide film through water transfer printing, so it is guaranteed that the graphene film can be uniformly and firmly dispersed on the surface of the polyimide film. According to the method, the cost of water transfer printing is low, the raw materials are environmentally friendly, produces no pollution and can be repeatedly used, and the prepared graphene heating film is excellent in heating performance, good in heating uniformity, sufficient in strength and lasting in graphene heating performance.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a graphene heating film prepared by water transfer printing and a preparation method thereof. Background technique [0002] Graphene has a perfect two-dimensional crystal structure, and its lattice is a hexagon surrounded by six carbon atoms, with a thickness of one atomic layer. The carbon atoms are connected by σ bonds, and the bonding method is sp2 hybridization. These σ bonds make graphene have extremely excellent mechanical properties and structural rigidity. Graphene is 100 times stronger than the best steel and even stronger than diamond. In graphene, each carbon atom has an unbonded p-electron, and these p-electrons can move freely in the crystal, and the movement speed is as high as 1 / 300 of the speed of light, which makes graphene have good conductivity. [0003] Graphene is a thin sheet composed of a layer of carbon atoms, and the carbon atoms are sp2 hybridized to ...
