Recently bacterial cellulose (BC) has attracted attention due to its unique physical and mechanical properties as well as its high purity and crystallinity, and wide potential applications such as electronic papers, fuel cells and medical materials. But it is difficult to process in solution state because of its large contents of intra- or inter-molecular hydrogen bonds. On the other hand, carbon nanotubes (CNTs) are being used as reinforcement in a wide variety of polymer matrix. In this study, we introduced CNTs to BC in order to enhance the mechanical properties of the regenerated BC fibers. The nanometer sized composite fibers were obtained by electrospinning of the solution prepared by regenerated BC dissolved in ionic liquids with acid-treated CNTs. The morphology of the composite fibers was observed by SEM and their conformational structures were studied by WAXD and FT-IR. |
