Abstract
The present invention belongs to the field of functional materials, and relates to a preparation method for a silver-loaded TEMPO oxidized nanocellulose/chitosan antibacterial preservative film for fruit and vegetable packaging, and the use thereof. The preparation method comprises: uniformly dispersing TEMPO oxidized nanocellulose, and adding a silver-ammonia solution thereto, so as to obtain a TEMPO oxidized nanocellulose, which immobilizes nano-silver, under microwave conditions; and dissolving chitosan in glacial acetic acid, adding the silver-loaded oxidized nanocellulose thereto, and using a casting evaporation method to prepare the TEMPO oxidized nanocellulose/chitosan composite film, which immobilizes nano-silver. In the present invention, the TEMPO oxidized nanocellulose is used as a reducing agent, a stabilizing agent and an immobilizing agent, such that no chemical reducing agent or stabilizing agent is added; the reduction efficiency is high, the cost is low, and toxicity is avoided; the microwave-assisted catalysis efficiency is high, and the energy consumption is low; and the immobilization effect of the nano-silver is improved by means of the film-forming property of the chitosan, such that the problem of cumulative toxicity caused by excessively fast release of the nano-silver is ameliorated, and the nano-silver is applied to the field of lasting antibacterial preservation of fruits and vegetables.
