Abstract

The invention relates to a preparation method of an electrothermal film, and belongs to the technical field of electrothermal materials. A metal chloride is prepared into a solution, dopamine is used to modify the metal chloride solution to obtain a mixed solution of the electrothermal film, graphene, gum and sulfate reducing bacteria are mixed for fermentation, under the effect of microbes, the graphene is combined with the gum, a binding force with resin is improved, nitrogen and sulfur elements are introduced into graphene molecules to enhance the stability of the graphene film, the mixed solution of the electrothermal film is injected on the basal body and serves as a bottom film, and one graphene layer is combined to obtain the electrothermal film. The prepared electrothermal film is high in stability and adhesive force, tends not to fall off the basal body, and has wide application prospects.

Description

technical field [0001] The invention relates to a method for preparing an electrothermal film, which belongs to the technical field of heating materials. Background technique [0002] Electric heating film is divided into high temperature and low temperature electric heating film. High temperature electric heating film is generally used in electronic appliances, military and so on. Low-temperature electric heating film is a translucent polyester film that can generate heat after being energized. It is made of conductive special ink and metal current-carrying strips, which are processed and hot-pressed between insulating polyester films. When working, the electric heating film is used as the heating body, and the heat is sent into the space in the form of radiation, so that the human body and objects are warmed first, and its comprehensive effect is better than the traditional convection heating method. The low-temperature radiation heating film system consists of a power s...
