摘要
基于细菌纤维素的多羟基结构,对其进行羧酸化改性;接着以羧酸化细菌纤维素为模板,原位复合聚吡咯(PPy),得到PPy/羧酸化细菌纤维素导电复合材料。并对其微观形貌、化学结构、热稳定性等进行测试表征,重点研究了用不同浓度的氧化剂处理后,复合材料电学性能的变化。结果表明,电子电导率随氧化程度的提高而升高,最高可达10^-3 S/cm,编号为0.04-48h的样品具有最佳的离子电导率。
In this research,bacterial cellulose was modified by carboxylate on the basis of its polyhydroxyl structure,and then the polypyrrole/carboxylated bacterial cellulose conductive composites were prepared by in-situ compounding with polypyrrole as a raw material and carboxylated bacterial cellulose as a template.The microstructure,chemical structure and thermal stability of the resulting composites were evaluated,and the effect of carboxylate degree on the electrical properties of the composites were investigated.The results indicated that the electronic conductivity of the composites increased with an increase of carboxylate degree,and it reached a maximum value of 10^-3 S/cm.The sample with a code of 0.04-48h achieved the optimum ionic conductivity.
