Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of demisting films, and in particular relates to a plurality of parallel graphene demisting films. Background Art
[0002] Graphene is a single layer of carbon atoms in sp 2 The two-dimensional crystalline material formed by hybrid bonding has excellent optical, electrical and mechanical properties; each of its carbon atoms has an unbonded electron, which can move freely within the atomic layer to form a half-filled π bond, giving graphene good conductivity and optical properties; the theoretical Young's modulus of graphene reaches 1.0TPa, and the inherent tensile strength is 130GPa, showing extremely high mechanical strength; in addition, the thermal conductivity of graphene is very high, making it a potential application prospect in the field of heat dissipation materials; defogging film is a thin film product used to eliminate fog on the glass surface; it is usually used in bathroom mirrors, car glass, eyeglass lenses and other fields to prevent water vapor from condensing on the surface to form fog; the working principle of the defogging film is to use a special coating material to make it difficult for water vapor to form droplets on the glass surface, thereby maintaining clear vision.
[0003] At present, the heating wire used in the existing defogging film is generally a single wire, and the single wire is set in the defogging film according to a specified shape. However, since the heating wire is a single wire and the existing voltage and current are relatively constant, there may be a situation where the current passing through the heating wire is too large, causing the heating wire to overheat, resulting in uneven heat distribution on the surface of the defogging film. Some areas may be overheated while other areas are relatively cold. In this way, the fog on the entire surface of the defogging film cannot be effectively removed, affecting the defogging efficiency of the defogging film. Based on this, a multi-group parallel graphene defogging film is proposed. Utility Model Content
