The Characterization of Electrospun PANI/PEO Nanofibers at Different Electrospinning Conditions at Room Temperature

Abstract

Nanofiber structures have wide usage area thanks to their excellent properties from sensor technologies, biomedical systems to tissue engineering, drug delivery systems. Electrospinning method is a versatile method that can produce very fine nanofibers with a simple production mechanism. On the other hand, it is important to optimize the fabrication parameters in order to obtain the appropriate nanofiber structure. In this study, PANI/PEO (Polyaniline/Polyethylene oxide) electrospun nanofibers are fabricated under ambient conditions and the effects of solution viscosity and collector rotation speed on fiber structure are discussed. Electrospun PANI/PEO nanofibers structures are investigated by scanning electron microscope (SEM). According to the SEM results, it is seen that the high viscosity nanofibers have straight and rigid structures. However, the low viscosity nanofiber structures break down at each collector speed, but the fiber orientations increase as the collector rotation speed increases. It is estimated that this study will be guide for future work on PANI.
