Abstract

The invention discloses a medicine packaging film and a preparation method thereof, wherein the medicine packaging film comprises a polymer film and a graphene coating coated on the polymer film, and the graphene coating comprises graphene and light-cured adhesive agent, the photocurable adhesive includes a hyperbranched cationic mussel-like polymer, and the hyperbranched cationic mussel-like polymer includes a poly-o-phenolic hydroxybenzophenone enamide monomer, a cationic monomer, and a photoresponsive unit body. The photocurable adhesive prepared by the hyperbranched cationic mussel-like polymer in the present invention significantly increases the bonding strength of the photocurable adhesive and the polymer film, thereby, the graphene composed of the photocurable adhesive and graphene The combination of the coating on the polymer film is stronger and the coating effect is better. At the same time, because the coating effect is significantly improved, the preparation process of the pharmaceutical packaging film is simplified to a certain extent.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a medicine packaging film and a preparation method thereof. Background technique [0002] As the main packaging material of pharmaceuticals, polymer film packaging materials have become more and more important in daily life. However, due to the influence of the plastic film production process and its own physical and chemical characteristics, it is difficult for the barrier properties of plastics to oxygen, water vapor, liquid substances and other low molecular weight substances to meet the requirements of most pharmaceutical packaging. The penetration of small molecular gases such as oxygen and water vapor into packaging materials will lead to oxidative deterioration of the active ingredients in the drug, which in turn will cause the reproduction of microorganisms and other phenomena. The direct consequence is that the shelf life of the drug is greatly shortened. Therefore, i...
