Wet Spinning of Graphene Oxide Fibers with Different MnO Additives.

We present the fabrication of graphene oxide (GO) and manganese dioxide (MnO) composite fibers via wet spinning processes, which entails the effects of MnO micromorphology and mass loading on the extrudability of GO/MnO spinning dope and on the properties of resulted composite fibers. Various sizes of rod and sea-urchin shaped MnO microparticles have been synthesized via hydrothermal reactions with different oxidants and hydrothermal conditions. Both the microparticle morphology and mass loading significantly affect the extrudability of the GO/MnO mixture.
