Abstract : Present work demonstrates the preparation of ultrathin nano electrospun fibers of Polyaniline (PANI)/polyvinyl
alcohol (PVA) with different concentration by electrospinning Method. To investigate the structural changes in PVA/PANI
electrospun fibers were studied by FTIR technique. The appearance of new peaks reveals the idea of proper blending for
polymers. The morphology and Ac electrical conductivity of ultrathin micro and nano electrospun fibers were investigated by
FESEM, HRTEM and Broadband Dielectric Impedance Spectroscopy techniques respectively. In the morphological studies
we attended the formation of uniform and complex bead-free nanofibers. The enhancement of frequency and temperature
dependent ac electrical conductivity was observed at higher concentration yielding 10-6
S/cm by the virtue of hopping
mechanism might be playing important role in the conduction process at higher frequency range due to high concentration of
PANI. The enough conductivity of PVA/PANI electrospun nanofibers with their complementary properties opens new
horizons towards electronics application.
