Abstract
Flexible nanodielectric are largely used in sensors and power sources for new generation of electronic devices. The most conventional methods used to design and manufacture these nanodielectric materials with desired properties are time-consuming and unable to determine interactions between the input parameters. In this study, a response surface methodology (RSM) is proposed to design polyvinylidene fluoride (PVDF)/barium titanate (BT) nanocomposites film prepared by ball milling process with optimized dielectric breakdown strength. Interaction effects of three individual control variables on nanocomposites dielectric strength were studied using RSM. Numerical optimization was employed to obtain the optimum factors for maximum dielectric breakdown strength. It is indicated that the optimum value of dielectric breakdown strength was 219.01 kV mm(-1), when input control factors were BT size of 6 nm, BT volume fraction of 10 vol% and milling time of 43.74 min.
