Abstract

The invention provides a macromolecule thin film material and a method for preparing the same. The macromolecule thin film material is prepared from graphene, macromolecule base materials, natural starch, functional monomers, stearic acid, paraffin, polyvinyl alcohol, sodium dodecyl sulfate, sodium carboxymethyl celluloses, additives, initiators, lactic acid, curing adhesive and water. The macromolecule thin film material and the method have the advantages that the processing cost of thin films can be reduced, the macromolecule thin film material is harmless for environments, is flexible, andis high in transparency and degradation rate and excellent in water vapor and oxygen barrier property and mechanical property, and the macromolecule thin film material and the method are wide in applicable range.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polymer film material and a preparation method thereof. Background technique [0002] Petrochemical resources such as petroleum and coal are decreasing day by day, and the waste of some polymer materials and the volatilization of organic solvents coexist with it, which is increasingly threatening the environment on which human beings depend. With the development of industry, chemically synthesized plastic products are widely used in the fields of food packaging and fresh-keeping because of their low price and stable properties. After use, they are difficult to degrade in the environment and cause "white pollution". In order to alleviate the adverse effects of "white pollution" on human survival, health and development, the research and development of green and environmentally friendly polymer film materials has gradually attracted attention. Environmental...
