The invention relates to the field of preparation of hydrogel films, in particular to a nanocellulose hydrogel film and a preparation method and application thereof. The invention provides a nano-crystalline cellulose hydrogel film. The nano-crystalline cellulose hydrogel film is composed of a net-shaped entanglement structure formed by interweaving nano-crystalline cellulose and aggregates of the nano-crystalline cellulose. The porosity of the nano cellulose hydrogel film is 90 to 94 percent; the thickness of the nano cellulose hydrogel thin film is 0.01 to 0.10 [mu] m. The super-hydrophilicity and high porosity of the nanocellulose hydrogel film provided by the invention ensure that liquid can quickly pass through, and the mutually cross-linked three-dimensional network structure effectively repels nanoparticles. Nanopores of the nanocellulose hydrogel film are entangled together, and nanofibers and nanofiber bundles are small and irregular and are not matched with larger nanoparticles. Therefore, the nanopores are not blocked by the nanoparticles, and liquid can smoothly pass through the nanocellulose hydrogel film.
