Nitrated bacterial cellulose (NBC) was synthesized from bacterial cellulose(BC) by nitric珠甀氀昀甀爀椀挀 acid method.The results showed that the network structure of BC were not obviously degraded by this method and the stability of nitrated bacterial cellulose reached the standard for A degree of nitrocellulose. The thermal decomposition activation energy calculated by differential scanning calorimetry results is 212.53 kJ/mol,and the thermal stability of nitrated bacterial cellulose is better than nitrocellulose.
