چکیده مقاله
Electrospun polyvinylidene fluoride (PVDF)/Graphene nanofibers are prepared in this work, for the first time. Fiber morphology is investigated using scanning electron microscopy (SEM) and Distribution of fiber diameter is also measured to confirm the Nano scale structure. FTIR spectroscopy is used to characterize the polymorphism in electrospun fibers. The influence of flow rate is investigated keeping constant the value of the applied voltage of 13 and 21 kV, and traveling distance of 17 cm. By increasing the flow rate from 0.5 to 1 ml/h fraction of β phase decreases slightly
