Conductive fibers are widely used in coatings and related applications. An effective production method is important. In this work, reduced graphene oxide (rGO) was added into the solution of poly(3,4-ethylenedioxythiophene) (PEDOT), poly(styrenesulfonate) (PSS) and polyvinyl alcohol (PVA). The rGO/PEDOT: PSS/PVA conductive nanofibers were prepared by electrospinning using a high-speed horizontal rotating collector instead of a traditional plane collector. The thermal behavior of composite nanofibers with rGO showed good stability compared with PEDOT: PSS/PVA nanofibers. The results show that the conductivity of nanofibers film was enhanced significantly by 100% when the content of 0.2% rGO in the PEDOT: PSS/PVA nanofiber. Further increase of rGO component content resulted in a limited increase in conductivity but with a sharp decline of the mechanical properties of the fibers. The tensile property of the nanofibers gained a significant improvement by 46.9% and 66.5% in the arc and radial direction, which indicates that high-speed horizontal rotating reception can make the texture more regular and stronger in the process of electrospinning.
