Abstract

Developments in technology are to design and manufacture devices of portable size which increases efficiency, reduces energy consumption and improves effectiveness. Fabrication of nanofibers of different polymer solution and their increasing use in wide range of applications is directing towards this. Out of different manufacturing techniques of nanofibers, electrospinning is the simpler, more productive and low-cost method. In this study, the nanofibers of polyvinylidene fluoride (PVDF) and amine functionalized multi-walled carbon nanotubes (MWCNT) in solvent Dimethyl formamide (DMF) are spun with the help of electrospinning technique at different combination of input parameters such as voltage, flow rate and distance between collector and syringe tip. Taguchi method of design of experiments (L9) is used for combination of these input parameters. Further, the diameter and morphology of collected nanofibers are studied with the help of SEM images. The objective is to understand the extent of influence that these parameters have on the nano-fibers diameter through statistical analysis. The results were compared with regression models and fuzzy networks predictions built for the same.
