In this study, the conductive conjugated polyvinyl alcohol (PVA)/graphene (G) composite nanofibers were fabricated by a facile electrospinning successfully. The processing technique demonstrated that the in-situ crosslinking nanofibers were hollow structures by using an ultrasonication treatment for G nanosheets (≈3.5 nm) due to the effect of solution viscosity (PVA-G concentration). Hereby, very few studies have been performed the characterization of the hollow nanofibers by PVA-G processing. The electrical conductivity and specific surface area of composite nanofibers resulted in significant effects on the viscosity of the reaction mixture for the electrospinning process, which can possibly open up the new emerging sensing themes and applications.
