Electrospinning is a well know technology for the production of nano and micro fibers. Graphene has been used in different fields due to its unique stability. Reduced graphene oxide (rGO) is prepared from the reduction of graphene oxide. In this work, we electrospun of Polyvinyl Alcohol (PVA) solutions with rGO to combine the different physical properties of the materials, on a rotating collector to verify the influence of the solutions and rotation on the morphology of the fibers. The optimization of the process highlighted the influence of the flow rate and tip-collector distance in relation to the rotation speed used.

Abstract
Electrospinning is a well know technology for the production of nano and micro fibers. Graphene has been used in different fields due to its unique stability. Reduced graphene oxide (rGO) is prepared from the reduction of graphene oxide. In this work, we electrospun of Polyvinyl Alcohol (PVA) solutions with rGO to combine the different physical properties of the materials, on a rotating collector to verify the influence of the solutions and rotation on the morphology of the fibers. The optimization of the process highlighted the influence of the flow rate and tip-collector distance in relation to the rotation speed used.File in questo prodotto:
