In the recent years, by developing the methodsof nanofibers formation, electro-centrifugal spinning hasbeen introduced as a new method of nanofibers fabrication.This nanofabrication technique is a combination of knowntechnique called electrospinning and a new coming methodcalled centrifugal spinning. This paper is a comparative studyamong conventional electrospinning, centrifugal spinningand the basis of electro-centrifugal spinning methods. Forinstance, although, the distance of nozzle to collector is acritical operating parameter to determining nanofibersdiameter in electrospinning method, it only shows an effecton the morphology and has no significant effect on the fiberdiameter in centrifugal spinning. Surface tension and viscosityof the solutions are the spinning-ability determinatives in thesethree methods which are affected by the type of polymers andsolvents and also the concentration of the solution, and needto be overcome through electrical or centrifugal forces orboth. The effective parameters on the process and the fibermorphology are investigated for each of the three methods
