Graphene fibers were fabricated through wet-spinning process using graphene oxide aqueous solution, which was used as starting materials to produce graphene/polyaniline blended fiber through in-situ polymerization of aniline on the surface of the them. Those blended fibers were applied on various conducting and flexible electronic devices for energy storage as well as wearable electronics.
The raw materials and corresponding process were analyzed through various analytic equipment, as FTIR, Ramon, TGA/DSC, XRD, SEM, TEM, XPS, and CV, etc. The preliminary results indicated that the blended fiber had core-shell structures, which presented superior performance of transporting electrons, and enhance the charge storage capabilities. Those materials show great potential on the applications of energy storage and wearable electronics.
