The invention discloses a high-temperature-resistant modified polypropylene film, and a preparation method and application thereof. The modified polypropylene film comprises a polypropylene film and an oxide layer and\/or a nitride layer on the surface of the polypropylene film; the thickness of the oxide layer or the nitride layer is 20-500nm. The thermal stability and high-temperature voltage resistance of the polypropylene film can be obviously improved by depositing an oxide layer or a nitride layer with proper thickness on the surface of the polypropylene film by using the ALD technology. The modified polypropylene film has high temperature resistance, such as 150 \u2103, has extremely small deformation amount at high temperature, can bear high breakdown voltage at high temperature, such as 580kV\/mm at 140 \u2103, and has wide application in the field of electronic products with high temperature requirements, such as capacitors.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
