Preparation and characterization of Poly(vinyl alcohol)/graphene nanofibers synthesized by electrospinning

摘要

We report on the synthesis and characterization of electrospun polyvinyl alcohol(PVA)/graphene nanofibers. The samples produced were characterized by Ramanspectroscopy for structural and defect density analysis, scanning electron microscopy(SEM) for morphological analysis, and thermogravimetric (TGA) for thermal analysis.SEM measurements show uniform hollow PVA fibers formation and excellent graphenedispersion within the fibers, while TGA measurements show the improved thermalstability of PVA in the presence of graphene. The synthesized polymer reinforcednanofibers have potential to serve in many different applications such as thermalmanagement, supercapacitor electrodes and biomedical materials for drug delivery.
