Study of structural and dielectric properties of blended poly (vinylidene fluoride) and poly(methyl methacrylate) multifunctional nanocomposites doped with nano-SnO2

The dielectric constant of polymers is low (low-ε′). A high-ε′ multifunctional nanomaterial must be added to the polymer in order to create a polymer composite with high values of the dielectric constant of the polymer blend. Composites prepared from such high-ε′ polymers are extremely beneficial for many energy storage devices and electrical devices such as transducers, piezo-sensors, hydrophones, microstrip antennas (used in artificial satellites for data detection) etc. In order to achieve the demands and needs of today for the society we prepared and design thin films using PMMA which is blended with poly vinylidene fluoride (PVDF) with high-ε′ value and further mixed with tin oxide (SnO2) nanoparticles in different weight ratios varies from 0.5 to 4 wt
