Abstract
In order to solve the problem of antibiotic‐resistant bacteria caused by excessive use of antibiotics, herein, an antibacterial membrane composed of natural sodium alginate (ALG), zeolite imidazolate skeleton (ZIF‐8) and niflumic acid (NIF) was reported. The membrane serves as a versatile platform for local antibacterial. This report carried out in‐depth research on the physical properties and antibacterial mechanism of the synthesized sodium alginate composite film. The data shows that the sodium alginate‐based antibacterial film has a continuous antibacterial effect, and the release of antibacterial molecules can be controlled according to changes in the external environment. The results show that the complex has stronger mechanical and bacteriostatic properties. Niflumic acid and Zn(II) have synergistic antibacterial effect. The complex promotes bacterial death by hindering bacterial respiratory metabolism and destroying cell membrane structure.
