dc.description.abstractFor using graphene in practical applications, it is crucial to transform the unique andindividual properties of graphene flakes into ordered macroscopic materials. The physical and chemicalproperties of macroscale graphene structures are closely related to the size of graphene flakes as buildingblocks. However, the chemical methods adopted to synthesize graphene oxide (GO) flakes offer no tightcontrol on the dimensionality of the ensuring flakes sizes. The goal of this study is to investigatemorphological evaluation of graphene based fibers fabricated using building blocks with different averagesize.. A facile and effective centrifugation method was carried out for size sorting of graphene oxide flakes.Macroscopic graphene oxide fibers were continuously spun from graphene oxide/water suspensionsfollowed by chemical and thermal reductions to obtain reduced graphene oxide fibers. All wet spinningparameters such as suspension concentration, injection rate and nozzle diameter were fixed to investigatethe effect of average building block size on the structural morphology of the fibers. Microscopicinvestigations revealed that the flake size have an enormous impact on the morphology of graphene oxidefibers. The increased average flake size results in the fibers with rectangular-like cross-section and increasedamount of voids within the graphene oxide fiber.
