Preparation of Polyurethane (PU)/Polyaniline (PANI) compound nanofiber via electrospinning

摘要

In this paper polyurethane (PU)/polyaniline (PANI) nanofibers were successfully prepared via electrospinning with N, N-dimethylformamide (DMF) and tetrahydrofuran (THF) mixture (1:2 mass ratio). The morphology, diameter and structure of the electrospun nanofibers were examined by scanning electron microscopy (SEM) and the diameter distribution of nanofibers was measured by Image-Pro Plus. Results indicate that the morphology, diameter and uniformity of the fibers were influenced by solution concentration, applied voltage, capillary-screen distance and flow rate greatly, and the finer and uniform nanofibers were electrospun from total solid content of the spinning solutions at 8 wt.%, PU and PANI with ratio of 10/1 (w/w), the spinning voltage at 35 kV, the collecting distance at 15 cm and the extruding speed at 6 ml/h.
