Bacterial cellulose (BC) naturally decomposes in the environment without releasing toxins or microplastics, making it a promising alternative to conventional plastics. However, its inherent brittleness after drying limits broader application. This study investigates four biobased plasticizers─epoxy soybean oil, castor tributyl citrate (TBC), and trans-aconitate (TBA)─to enhance flexibility of BC through situ modification. By combining gel-assisted biosynthesis with an spray plasticization method, plasticizers are uniformly incorporated into nanofiber network BC, resulting films significantly improved transparency. Among plasticizers, TBC TBA showed most effective plasticization, increasing E% 9.63 11.90%, respectively, corresponding 6.3-fold 7.5-fold enhancements compared control. approach not only improves mechanical properties but also streamlines production by enabling simplified processing method. The findings underscore potential plasticized biomaterials replacing fossil-based plastics advancing development sustainable materials.
