Abstract

The present application discloses membranes and methods of making them. The film includes: a base layer, a first barrier layer disposed on the surface of the base layer, and a second barrier layer disposed on the surface of the first barrier layer, wherein: the second barrier layer includes two-dimensional nanomaterials and high molecular material. Since the material particle size of the two-dimensional nanomaterial belongs to the nanoscale, compared with the first barrier layer, the second barrier layer has higher compactness and smaller pore size, and adding the second barrier layer on the first barrier layer can The overall sealing performance of the membrane is increased, thereby solving the problems in the prior art.

Description

Technical field [0001] The present application relates to the field of materials processing technology, and in particular relates to a membrane preparation. Background technique [0002] With the development of society, the sealing process food, beverage bottle, pharmaceutical, electronics and optical industries, it is generally required to use a plastic film, a metal foil film. Limited to the conventional membrane material preparation, preparation process, etc., is generally formed fine pores, pinholes, cracks in the surface, thus affecting the sealing properties of the film. It is necessary to provide more film with excellent sealing properties, in order to solve the problems of the prior art. Inventive content [0003] Embodiments of the present application provides a film and method for solving the problem of poor film sealing performance of the prior art. [0004] Example embodiments of the present application provides a method for preparing a film, comprising: [0005] Pro...
