Photocatalytic polylactic acid antibacterial film and preparation method and application thereof |
| abstract |
The invention provides a photocatalytic polylactic acid antibacterial film and a preparation method and application thereof. The invention uses low-temperature plasma technology to modify the surface of polylactic acid material, so that a large number of active carboxyl groups are generated on the surface. The carboxyl group on the surface of the polylactic acid film is innovatively covalently reacted with the photosensitizer, and combined with blue LED light irradiation to prepare a photocatalytic PLA antibacterial film; the invention organically combines photodynamic technology, low-temperature plasma technology and food packaging. The integrated innovation of materials and the development of packaging film materials with efficient sterilization function are a breakthrough in the food packaging industry, and also provide new theoretical ideas and innovative practices for the future development of functional food packaging film materials; the antibacterial film of the present invention is a green Food packaging materials that efficiently kill pathogenic bacteria and spoilage bacteria commonly found in food, and further use these new packaging films for packaging salmon and other foods, greatly extending the shelf life of food. |
