This study aimed to produce cellulose-based conductive fabrics with electrical conductivity and flexibility. Bacterial cellulose (BC) and three chemical cellulose (CC), namely methyl cellulose (MC), hydroxypropyl cellulose (HPMC) and carboxymethyl cellulose (CMC) were in situ polymerized with aniline and the four conductive cellulose fabrics were compared and evaluated. Matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy analysis confirmed that three CC-PANI composites displayed longer and more stable polymerization pattern than BC-PANI because of the different polymerization method: bulk polymerization for BC-PANI and emulsion polymerization for CC-PANI, respectively. The electrical conductivity of BC-PANI and CC-PANI were ranging from 0.962 × 10-2 S/cm to 2.840 × 10-2 S/cm. MC-PANI showed the highest electrical conductivity among the four conductive cellulose fabrics. The flexibility and crease recovery results showed that MC-PANI had the highest flexibility compared to BC-PANI, HPMC-PANI, and CMC-PANI. These results have confirmed that the electrical conductivity and flexibility were influenced by the type of cellulose, and MC-PANI was found to have the best performance in the electrical conductivity and flexibility.
本研究旨在制备具有导电性和柔韧性的纤维素基导电织物。将细菌纤维素（BC）和三种化学纤维素（CC），即甲基纤维素（MC）、羟丙基纤维素（HPMC）和羧甲基纤维素（CMC）与苯胺原位聚合，并对四种导电纤维素织物进行了比较和评估。基质辅助激光解吸/电离飞行时间质谱分析证实，由于聚合方法不同，三种 CC-PANI 复合材料比 BC-PANI 具有更长、更稳定的聚合模式：BC-PANI 为本体聚合，CC-PANI 为乳液聚合。BC-PANI 和 CC-PANI 的电导率在 0.962×10-2 S/cm 到 2.840×10-2 S/cm 之间。MC-PANI 在四种导电纤维素织物中表现出最高的电导率。柔韧性和折痕恢复结果表明，与 BC-PANI、HPMC-PANI 和 CMC-PANI 相比，MC-PANI 的柔韧性最高。这些结果证实了电导率和柔韧性受纤维素类型的影响，并且 MC-PANI 在电导率和柔韧性方面表现出最佳性能。
