Tailoring surface of fibers has been attracting the attention of researchers in different fields and applications. Nowadays, appreciations to the electrospinning technique, polymeric nanofibers are easily producible. The electrospinning process has been prominently investigated and developed during the last decade. The influence of working parameters on the secondary surface morphology of electrospun fibers is very significant. In this study, the effect of processing parameters (applied voltage, flow rate, distance between the tip of the needle and the collector (DTC), diameter of the needle, and rotation speed of the drum collector) on the secondary surface morphology (e.g. porous, grooved, and rough) of electrospun poly (vinylidene fluoride) (PVDF) fibers are studied. The results indicate that the secondary surface morphology of electrospun PVDF fibers can be alerted by maneuvering applied voltage, flow rate, DTC, and rotation speed of the drum collector. However, there is no relationship between the secondary surface morphology of electrospun PVDF fibers and the diameter of the needle. Importantly, fibers with different secondary surface morphologies have the ability to be served in different applications such as energy harvesting, oil cleanup, filtration, and so on. We believe this study can be served as a good reference for generating electrospun fibers with the desired structure by controlling the processing parameters.
