Abstract

The invention discloses a preparation method of a self restoration antibacterial microcapsule film based on host-guest interaction. Firstly, ferrocene (Fc) is successfully modified onto a branch chainof polyacrylic acid (PAA) to form PAA-Fc polymers; then, micro capsules (PAH / PSS) are carried with different concentrations of chloromycetin; through a layer-by-layer self assembly technology, a substrate material is firstly soaked into a PAA-Fc solution for a period of time; after being taken out, the substrate material is flushed by ultrapure water and is then soaked into a beta-cyclodextrin branched polyethylenimine (beta-CD-PEI) solution for a period of time; after being taken out, the substrate material is flushed by ultrapure water and is then soaked into a medicine-carrying microcapsule for a period of time; a multilayer functional nanometer medicine-carrying microcapsule film is repeatedly assembled on the substrate for multiple times. The method has the advantages that convenience is realized; the cost is low; the prepared medicine-carrying microcapsule host-guest film has good self restoration functions, medicine release functions and antibacterial functions.

Description

technical field

[0001] The invention relates to a method for preparing a self-repairing antibacterial microcapsule film based on host-guest interaction. Based on layer-by-layer self-assembly technology, a new driving force-host-guest interaction is developed, and microcapsules wrapped with chloramphenicol are introduced at the same time. The microcapsule host-guest film material not only has self-healing function, but also has excellent drug release function and antibacterial function, which can be applied to food packaging, fine cosmetics, drug transportation and other fields. Background technique

[0002] Under suitable temperature and humidity conditions, microorganisms can grow and reproduce in large numbers. For example, food is contaminated by microorganisms during production, transportation, storage, etc., and thus oxidized and cannot be stored for a long time; for example, wounds are susceptible to microbial infection in the external environment, resulting in The wou...
