Bacterial cellulose (BC) is a biomaterial with many excellent properties, but its application as a food packaging and biomedical material is limited due to its lack of antibacterial properties. In this study, ferulic acid (FA) grafted self‐assembled bacterial cellulose‐chitosan (BCF) membranes were prepared by soaking BC films in chitosan‐ferulic acid (CF) solution to synthesize antibacterial biomaterials. 1 H NMR confirmed that FA grafted onto chitosan successfully. The results of field emission scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, and tensile analysis showed that CF were successfully incorporated into BC matrix and the BCF membranes had good physical properties. The antibacterial experiments demonstrated that BCF membranes had an excellent antibacterial effect against Staphylococcus aureus and Escherichia coli . Therefore, combining all these properties, BCF composite membranes would have potential application in food packaging or wound‐healing materials.
