Abstract: Bacterial cellulose (BC) is nanocellulose, usually produced by Acetobacter xylinum in form of interconnected networks of cellulose nanofibers. BC has many advantages such as excellent mechanical strength, very high modulus and tensile strength, and biocompatibility, but low breaking elongation. On the other hand, natural rubber (NR) is well-known for its outstanding elastic properties. Therefore, in order to improve stretch ability of BC film, a composite film of BC and NR has been developed in this study. The BC pellicles were produced by A. xylinum using coconut-water medium under static incubation for 7 days. The BC pellicles were then purified and immersed in NR latex solution at various concentrations (0-10 % dry rubber content (drc)). Effect of temperature on the immersion was also investigated. The main objective of this study is to develop the appropriate immersing conditions and investigate their effects on physical properties of the BC-NR composite films. The results from SEM show higher accumulation of NR in nanocellulose fiber networks by the immersion at 60°C as compared with those at a room temperature (30°C). The mechanical properties analyzed by UTM (HM10) show significant improvement in both tensile strength and elongation at break of the composite BC-NR films.
