Abstract Electrospinning is a process of production fibers with diameters ranging from the submicron down to the nanometer size by applying a high voltage to a polymer solution. The important parameters in the morphology of electrospun polymer fibers are polymer structure, polymer solution properties, processing conditions, and ambient parameters. In the present work electrospinning of polyacrylonitrile (PAN) has been attempted to generate uniform nanofibers without beads. Electrospinning was performed at various concentrations ranging from 4 to 18 w/v%. The effects of polymer solution properties on electrospinnability of the PAN/DMF solutions have investigated. Fiber morphology was observed under a scanning electron microscopy (SEM). For the polymer electrospun from low concentration (Be<2), polymer droplets have formed. For the polymer electrospun from semi-dilute solution concentration (24. The relationship between solution viscosity and its concentration is in the form: η 0.0205C4.16 and relation between the diameter of electro-spun the PAN nanofiber and solution concentration is in the form: d 0.0326C3.45.
