Light-weight graphene conductive thin film and preparation method thereof

Abstract

The invention discloses a light-weight graphene conductive thin film and a preparation method thereof. The light-weight graphene conductive thin film is prepared from the following raw materials in parts by weight: 10 to 14 parts of organic calcium carbonate, 0.5 to 1 part of 2-mercapto benzimidazole, 1 to 2 parts of coco fatty acid diethanol amide, 5 to 6 parts of graphene oxide, 80 to 90 parts of polyaniline, 2 to 3 parts of borax, 0.8 to 1 part of calcium ricinoleate, 3 to 4 parts of phosphorus trichloride, 2 to 3 parts of pentaerythritol, 0.1 to 0.2 part of hexamethylcyclotrisiloxane, and0.8 to 1 part of barium stearate. The light-weight graphene conductive thin film has the advantages that the graphene and the calcium carbonate are blended and combined, so that the mechanical strength of the finished material is improved; by modifying the surface, the dispersing uniformity is realized, and the mechanical stability strength of the finished product is improved; by adding the graphene, the stable conductive property of the finished thin film is realized.

Therefore, polymers gradually appear in the market Conductive materials, including polyaniline, polypyridine, etc., polyaniline is widely used due to its good stability in the air, easy access to raw materials, cheap monomers, simple synthesis methods, and easy adjustment of conductivity, such as electrode materials , electrochromic materials, metal anti-corrosion materials, electromagnetic shielding materials, anti-static materials, molecular devices, etc., but because polyaniline has the disadvantages of low mechanical strength and poor mechanical properties; at the same time, the use of inorganic particles to enhance polyaniline is easy to cause particles agglomeration, thereby reducing the mechanical stability of the finished film
