Acetylated polyester modified electroconductive film and preparation method thereof

Abstract

The invention discloses an acetylated polyester modified electroconductive film. The acetylated polyester modified electroconductive film comprises raw materials in parts by weight as follows: 3-4 parts of acetic anhydride, 0.01-0.02 parts of a catalyst, 30-40 parts of methyl methacrylate, 10-15 parts of butyl acrylate, 1-2 parts of ammonium persulfate, 170-200 parts of polyphenyl ether, 1-2 partsof alkylolamide, 0.4-1 part of 8-hydroxyquinoline, 2-3 parts of silane coupling agent kh550, 10-13 parts of light calcium carbonate and 300-400 parts of a solvent. The preparation method comprises the following steps: calcium carbonate is treated with amino silane, acetic anhydride and methyl methacrylate are blended, acetylation modification is performed under the catalytic action of concentrated sulfuric acid, modified monomers are polymerized under the action of an initiator, amino calcium carbonate is introduced in the polymerization process, and dispersion compatibility of calcium carbonate in polyester is improved.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to an acetylated polyester modified conductive film and a preparation method thereof. Background technique [0002] Conductive film is a very important optoelectronic material, which 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 films are widely used in the field of solar cells, which have good light transmittance, low resistivity, and good chemical temperature resistance. However, as inorganic fillers, the films are brittle, poor in toughness, and relatively high in synthesis temperature. High, these all limit their further development, therefore, polymer conductive materials gradually appear in the market, including polyaniline, polypyridine, etc., because polyaniline has good stability in the air, raw materials are easily available, and the ...

Problems solved by technology

At present, inorganic oxide films are widely used in the field of solar cells, which have good light transmittance, low resistivity, and good chemical temperature resistance. However, as inorganic fillers, the films are brittle, poor in toughness, and relatively high in synthesis temperature. High, these all limit their further development, therefore, polymer conductive materials gradually appear in the market, including polyaniline, polypyridine, etc., because polyaniline has good stability in the air, raw materials are easily available, and the monomer price is cheap , The synthesis method is simple, the conductivity is easy to adjust, etc., and it is widely used, such as electrode materials, electrochromic materials, metal anti-corrosion materials, electromagnetic shielding materials, anti-static materials, molecular devices, etc. However, due to inorganic raw materials and polymer polymerization The poor compatibility of materials makes it difficult for composite materials to be blended into films, and the mechanical properties of the obtained single organic film are relatively reduced.
