Abstract

Development of self-assembly routes for long-range organization of graphene oxide (GO) is an active field of research due to the enormous potential and diverse applications of this carbonaceous material. We present a simple strategy for producing anisotropic GO assemblies through utilizing electrospun polymer fibers as a physical template. We demonstrate that intertwined uniform electrospun microfibers comprising a mixture of polyethylenimine (PEI) and polyvinylpyrrolidone (PVP) constituted docking sites for GO flakes through electrostatic attraction between the negatively-charged GO and positive amine-displaying polymer fibers. The reduced GO (r-GO) network formed after chemical reduction exhibited electrical conductivity and optical transparency, opening the way for varied electro-optical applications.
