NOVELTY - The nanometer plasma modified fluorine-containing high resistant solar battery back film comprises a polyethylene terephthalate (PET) base material (4). The PET base material is provided with: fluorine-containing coating or fluorine-containing polymer thin film or a coating layer (10-50 mu m); and an inner side of a polyolefin layer between the PET base material and the fluorine coating or fluorine-containing polymer thin film, where a graft layer (1-5 mu m) and the PET base material are connected with a first bonding layer.    USE - Used as a nanometer plasma modified fluorine-containing high resistant solar battery back film.    ADVANTAGE - The nanometer plasma modified fluorine-containing high resistant solar battery back film has good interlayer peeling strength.    DETAILED DESCRIPTION - The nanometer plasma modified fluorine-containing high resistant solar battery back film comprises a polyethylene terephthalate (PET) base material (4). The PET base material is provided with: fluorine-containing coating or fluorine-containing polymer thin film or a coating layer (10-50 mu m); and an inner side of a polyolefin layer between the PET base material and the fluorine coating or fluorine-containing polymer thin film, where a graft layer (1-5 mu m) and the PET base material are connected with a first bonding layer. The PET base material and the polyolefin layer are provided with a first adhesive layer (3) and a second adhesive layer (5). The PET base material has a thickness of 100-300 mm. The polyolefin layer has a thickness of 20-150 microns. The first and second bonding layers have a thickness of 5-15 mu m. An INDEPENDENT CLAIM is included for a method for preparing nanometer plasma modified fluorine-containing high resistant solar battery back film.
