Anti-impact conductive film and preparation method thereof

Abstract

The invention discloses an anti-impact conductive film, which is prepared from the following raw materials in parts by weight: 110-130 parts of polytetrafluoroethylene, 10-16 parts of carbon nanotubes, 0.8-1 part of diphenyl imidazoline, 4-6 parts of polyamide wax micro-power, 0.7-1 part of 6-hydroxy-2-naphthoic acid, 1-2 parts of dodecyl dimethyl betaine, 4-5 parts of polyethylene glycol, 1-2 parts of zinc stearate, 3-4 parts of oleic acid polyoxyethylene ester and 10-13 parts of polyaniline. The nanotubes are firstly processed by adopting a diphenyl imidazoline ethanol solution and then dispersed into an amide solution, so that surface activity of the nanotubes are effectively improved, the aggregation is effectively reduced, and the mechanical stability of the finished film is improved.

[0002] Conductive thin film is a very important optoelectronic material. It has the characteristics of low resistance and is widely used in various optoelectronic materials such as solar cells, electrode materials, and displays. At present, inorganic oxide thin films are widely used. Good chemical resistance, low resistivity, good chemical temperature resistance, but as an inorganic filler, its film has high brittleness, poor toughness, and high synthesis temperature, all of which limit their further development. 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 due to the rigidity of polyaniline chains and the strong interaction between chains, its solubility is extremely poor, almost insoluble in solvents Therefore, its wide application in technology is limited, and at the same time, polyaniline has the disadvantages of low mechanical strength and poor mechanical properties;
