This dissertation is concerned with the properties of polymer graphene composite fibres. Raman spectroscopy has been considered as a powerful technique to characterise the graphene-containing fibres.Electrospinning is used to fabricate poly (vinyl alcohol) (PVA) nanofibres. The effect of the processing conditions including the PVA concentration, electric voltage, tip-to-collector (DTC), flow rate, N, N methylpyrrolidone (NMP) solvent concentration and graphene flakes. A details study has been undertaken the morphology and diameter of the PVA electrospun fibres containing graphene flakes. Scanning electron microscopy (SEM) has been used to investigate the structure of polymer fibres. Raman spectroscopy has been used to identify the few-layers graphene sheets in PVA nano-fibres.
