Influence of Process Parameters on Electrospun Nanofibre Morphology

摘要

This research work reports on the influence of process parameters like voltage, spinning electrode speed, distance between electrodes and solution concentration on the morphology and tensile properties of electrospun nanofibrous PVA webs. The electrospinng spinning assignment is carried out with the commercially available Nanospinder machine. The morphological developments are explained on the basis of nanofibre diameter and web density as depicted by the FESEM images. The tensile properties are measured in terms of the mean tensile stress and Young's modulus. The influence of individual parameters in isolation is studied herewith for assessing their individual influence and accordingly can be put together in order to control the process for proper development of nano webs morphology. The correlation of morphological developments and tensile properties is brought out for deciding the effective combination of process parameters in order to obtain stronger nanofibrous webs.
