| description | The invention discloses a polyvinyl chloride-based energy storage dielectric material as well as a preparation method and application thereof, and belongs to the technical field of energy storage dielectrics for thin-film capacitors. The preparation method comprises the following steps: under a stirring condition, heating polyvinyl chloride, a solvent, a catalyst and an alkyl (meth) acrylate monomer at 80-120 DEG C for polymerization reaction for 1-24 hours; and diluting the reaction liquid, removing the catalyst, adding the reaction liquid into a poor solvent, and precipitating to obtain the polyvinyl chloride grafted (methyl) alkyl acrylate grafted copolymer. According to the invention, a controllable grafting method is adopted to obtain a polyvinyl chloride grafted polymer; and the variety and the length of the branch chain can be well controlled. The method is easy to operate and high in practicability; the polyvinyl chloride-based polymer dielectric material prepared by the invention has excellent electr |
