UNLABELLED
Electrically conducting bacterial cellulose (BC) membranes were prepared by ex situ incorporation of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (
PEDOT
PSS) into BC pellicles. The BC pellicles were immersed into an aqueous solution of
PEDOT
PSS for 6, 12, 18, or 24h, and the resultant composites were vacuum dried at ambient temperature. The structural features of the composites were determined using X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM), Fourier-transform infrared (FTIR) spectroscopy, and X-ray diffraction (XRD). XPS confirmed synthesis of the composites, and SEM showed uniform incorporation of
PEDOT
PSS into the BC matrix. The FTIR spectra of the composites exhibited characteristic bands for both BC and
PEDOT
PSS, and XRD analysis showed a slight decrease in crystallinity during composite preparation. The electrical conductivity of the composites was 12.17S/cm for incorporation of 31.24 wt%
PEDOT
PSS into the BC matrix. These highly conducting BC-PEDOT:PSS composites are expected to find potential applications in optoelectronic devices such as biosensors, organic light-emitting diodes, and solar cells.

通过将聚（3,4-亚乙基二氧噻吩）-聚（苯乙烯磺酸盐）（PEDOT：PSS）掺入细菌纤维素（BC）膜中，制备出了导电的 BC 膜。BC 膜浸入 PEDOT：PSS 的水溶液中 6、12、18 或 24 小时，然后在环境温度下真空干燥得到的复合材料。使用 X 射线光电子能谱（XPS）、场发射扫描电子显微镜（FE-SEM）、傅里叶变换红外（FTIR）光谱和 X 射线衍射（XRD）来确定复合材料的结构特征。XPS 证实了复合材料的合成，SEM 显示了 PEDOT：PSS 均匀地掺入 BC 基质中。复合材料的 FTIR 光谱显示了 BC 和 PEDOT：PSS 的特征谱带，XRD 分析表明在复合材料制备过程中结晶度略有下降。将 31.24wt%的 PEDOT：PSS 掺入 BC 基质中，复合材料的电导率为 12.17S/cm。这些高导电的 BC-PEDOT：PSS 复合材料有望在光电设备中找到潜在的应用，如生物传感器、有机发光二极管和太阳能电池。
