A large quantity of perishable muscle food is being wasted due to harmful bacteria infestation during the sales and circulation each year facing challenges. In this study, a self-activated bactericidal active film (PLA/g-C3N4@PCN-224) responsive fresh lamp light was prepared, which showed excellent hydrophobicity, water vapor resistance, thermal stability. Due synergistic effect between light-induced reactive oxygen species high specific surface area g-C3N4@PCN-224, still maintains 99.99% efficacy against Escherichia coli Staphylococcus aureus after 10 days continuous activity test. The results cell hemolysis experiments indicated that safe nontoxic can effectively preserve pork for 7 days. Moreover, also exhibited recyclable efficient killing activity. strategy achieving ultrapersistent freshness provided.
