Abstract:
The present article reports on dielectric properties of a tertiary nanocomposite system, composed of poly (vinylidene fluoride) (PVDF), BHF (BaFe 12 O 19 ) and reduced graphene oxides (rGOs). The 0.90(PVdF)-0.1[(1-x)bHF x(rGO)] nanocomposites thick films were prepared by solution cast method. This tertiary compound has been prepared to explore the possible use in high energy density capacitor. The crystal symmetry modifications due to reduced graphene oxide, BHF and PVDF interaction have been studied by employing the X-ray diffraction (XRD) and FTIR analysis. The dielectric constant and dielectric loss of the tertiary nanocomposite thick film has been studied with frequency variations from 100 Hz to 10 MHz at different temperatures range from 300 K to 400 K. A very high dielectric constant has been observed for 0.90(PVDF)-0.1[(0.95)BHF-(0.05)rGO] in tertiary nanocomposites of 0.90(PVDF)-0.1[(1-x)BHF x(rGO)], which is the percolation threshold value of the nanocomposites

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
