▎ 摘　　要

NOVELTY - Macromolecule nano-composite voltage resistance soft thin film comprises 100 pts. wt. high-molecular polymer base material and 3-14 pts. wt. nano-conductive filler. The nano-conductive filler is surface-modified graphene nano sheet or graphene powder. The high-molecular polymer base material is elastomers, rubber, mixed material of metallocene linear polyethylene with low density polyethylene and/or mixed material of metallocene linear polyethylene with polyethylene of similar physical properties. The metallocene linear polyethylene accounts to 50-70% of the total wt. of the base material. USE - Used as a macromolecule nano-composite voltage resistance soft thin film. ADVANTAGE - The film has flexibility, high mechanical strength and stiffness, corrosion, oxidation, impact and tear resistance, balanced tensile force, and can be cut into required shape and size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the soft thin film comprising: (i) mixing elastomers, rubber, mixed material of metallocene linear polyethylene with low density polyethylene and/or mixed material of metallocene linear polyethylene with polyethylene of similar physical properties to obtain the high-molecular polymer base material; (ii) adding nano-conductive filler accounting to 99-95% of the wt. of nano-graphene in a high speed mixer, simultaneously adding 1-5% polyurethane reactive groups and epoxy resin, performing anchored modification of nano-graphene and the nano-conductive filler; and (iii) melt blending polymer base material and nano-conductive filler to obtain high molecular nanocomposite voltage resistance material, then hot melting, rolling, and cold stereotyping to obtain soft film of required thickness.
