A morphology study of PA 6 electrospun nanofibers using single and double side nozzles jet

In this investigation the effects of some parameters such as voltage, distance between nozzle and collector and polymer solution concentration in the single nozzle electrospinning of PA 6 nanofibers were studied. Then according to optimized condition of electrospinning, the morphology of nanofibers web (diameters and their evenness) which electrospun with one and double side nozzles were considered. The results showed that the most effective parameter on nanofibers diameter is polymer solution concentration. Average diameter of nanofibers decreased with decreasing the polymer solution concentration. Average diameter of nanofibers produced with double side nozzles electrospinning is more uniform comparing with the nanofibers webs produced with single nozzles electrospinning. Accordingly, the electrospinning with double side nozzles is suitable method for producing the higher amount of nanofibers at short time.
