Preparation of PANi/PEO micro/nanofibers by electrsopinning

The PANi/PEO micro/nanofibers are prepared via electrsopinning in this study.The influences of the ratio of PANi/PEO in spinning solution,spinning voltage,flow speed and spinneret diameter on the fiber morphology are studied.The results show that the fiber-forming ability of the spinning solution enhances and the fiber's average diameter increases with the increasing of PEO content.The increasing of the spinning voltage is conducive to the refinement of the fibers but enhances the phenomenon of broken filaments.The average diameter of the fibers increases with the increasing of the injection velocity and the spinneret diameter.The diameter of obtained PANi/PEO fiber is distributed in 256-812 nm.
