Eco-friendly conductive polymer nanocomposites have garnered attention as an effective alternative for conventional conductive nanocomposites. Here, we report the fabrication and optimization of flexible, self-standing, and conductive bacterial cellulose/poly(3,4-ethylene dioxythiophene) (BC/PEDOT) nanocomposites using the vapor phase polymerization (VPP) method. Eco-friendly bacterial cellulose (BC) is used as a flexible matrix, and the highly conductive PEDOT polymer is introduced into the BC matrix to achieve electronic conductivity. We demonstrate that vapor phase polymerized BC/PEDOT composites exhibit more than 10 times lower sheet resistance (18 Ω/square) compared to solution polymerized BC/PEDOT (188 Ω/square). The resultant BC/PEDOT fabricated could be bent up to 100 times and completely rolled up without a notable decrease in electronic performance. Moreover, bent BC/PEDOT films enable operation of a green light-emitting diode (LED) light, indicating the flexibility and stability of conductive BC/PEDOT films. Overall, this study suggests a strategy for the development of eco-friendly, flexible, and conductive nanocomposite films.

作为传统导电纳米复合材料的有效替代品，环保型导电聚合物纳米复合材料已引起关注。在这里，我们报告使用气相聚合（VPP）方法制备和优化柔性，自立和导电细菌纤维素/聚（3,4-乙撑二氧噻吩）（BC / PEDOT）纳米复合材料。环保细菌细菌纤维素（BC）被用作柔性基质，高导电性PEDOT聚合物被引入BC基质中以实现电子导电性。我们证明，与溶液聚合的BC / PEDOT（188Ω/平方）相比，气相聚合的BC / PEDOT复合材料的薄层电阻（18Ω/平方）降低10倍以上。制成的BC / PEDOT可以弯曲多达100次并完全卷起，而电子性能没有明显下降。此外，弯曲的BC / PEDOT膜使绿色发光二极管（LED）灯工作，表明导电BC / PEDOT膜的柔韧性和稳定性。总体而言，这项研究提出了开发环保，柔性和导电纳米复合薄膜的策略。
