The graphene oxide is successfully prepared by applying the modified Hummers method. Poly (vinylidene fluoride)–Graphene oxide nanofiber membranes are synthesized with electrospinning technique. The prepared nanofiber membranes are carefully examined to ensure their single phase and compound structure formation as well as to measure their equivalent membrane diameter distributions. The samples were characterized with several tools like XRD, FTIR, and FESEM to prove their purity and to discover the samples microstructure. The corresponding cyclic mechanical properties are tested with the Dynamic Mechanical Analyzer (static mode).The graphene oxide is successfully prepared by applying the modified Hummers method.
