Disclosed are an oxidized graphene nano-ribbon/polymer composite film and a preparation method therefor. A multi-walled carbon nano-tube is longitudinally cut into oxidized graphene nano-ribbons with strip-shaped structures through an oxidation method, and then the oxidized graphene nano-ribbons are compounded with a polymer to form the film. The composite film prepared according to the invention is excellent in barrier property and mechanical property, and has a certain fixed degree of transparency, thereby being widely applied to the field with higher barrier requirements. At present, mass production of carbon nano-tubes is realized in domestic and foreign countries, so that the preparation cost of the oxidized graphene nano-ribbon is greatly reduced. The barrier property and mechanical property of the composite film can be greatly improved only with few oxidized graphene nano-ribbons. The preparation method is simple, high in operability, and is suitable for large-scale industrialized production. |
