| 摘 要： | 以细菌纤维素为原料,用硝硫混酸法合成出硝化细菌纤维素(NBC)。结果表明,采用硝硫混酸法合成硝化细菌纤维素未造成细菌纤维素的网状结构明显断裂降解,且合成出的硝化细菌纤维素安定性能达到A级硝化纤维素标准。用差示扫描量热法对产物进行了表征,并计算出硝化细菌纤维素的热分解活化能为212.53kJ/mol,表明硝化细菌纤维素热的稳定性优于硝化棉。

| Abstract: | Nitrated bacterial cellulose(NBC)was synthesized from bacterial cellulose(BC)by nitric-sulfuric 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 212.53kJ/mol,and the thermal stability of nitrated bacterial cellulose is better than nitrocellulose. |
