Optimization of Process Parameters for Enhancement of β Crystal content in Thin Films

The purpose of this research work was to optimize the process parameterslike Multi Walled Carbon Nanotube (MWCNT) loading, Spin coating speed and Ultrasonication time for enhancement in β phase crystal content of Polyvinylidene fluoride (PVDF) /MWCNT thin films using Taguchi L9 array technique. The thin films were synthesized by spin coating technique and were characterized byFourier transform infrared(FTIR), X-Ray Diffraction (XRD), Scanning electron microscope (SEM) techniques. Maximum of 82.04% of β crystals were formed in specimen S3 (0.1wt. %, 1000rpm, 90min). Analysis of Variance (ANOVA) &Response Surface Methodology(RSM)weredone using Minitab V16 to optimize the process parameters.
