In situ Nano-assembly of Bacterial cellulose/ Polyaniline
Bacterial cellulose (BC)，produced by Acetobacter xylinum，consists of ribbon-shaped nano-fibers in web-like structures. Polyaniline (PANI) is a kind of conductive polymers that extensively used in solar cell, sensor devices etc. The conductivity is related to the process of synthesis and doping. In this paper, the novel bacterial cellulose/polyaniline (BC/PANI) composites have been in situ nano-assembled. The morphology, supermolecular structure, mechanical and conducting properties of the composites were characterized by Fourier transform Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Field Scanning Electron Microscope (FSEM), stress strain gauge and the measurement for the resistance. The results demonstrated that electronic molecules could be assembled into a 3D cellulose network of nano-fibers, the conducting ability of the composites were significantly improved. It is possible to develop a new material with high conductivity and good mechanical properties that may be applied in flexible displays or biosensors.
