The significance of this method lies in the tiniest diameter of fibers that can be produced because nanofibers provide more performance advantages in various fields and area as their diameters decrease. Different parameters of electrospinning (solution parameters, process parameters, and ambient parameters) play a vital role in determining the diameter of electrospun nanofibers. In this work, the relationship between the needle diameter and diameter of electrospun poly (vinylidene fluoride) (PVDF) nanofibers is investigated. The results show that there is a positive relationship between the needle diameter and the diameter of electrospun PVDF nanofibers. 2021 26 32 962 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJBES.040201 https://www.americaspg.com/journal/22/article/962 https://www.americaspg.com/storage/51775592258.pdf
