Abstract Zinc ferrite nanocrystalline powder was obtained by solid state synthesis of starting zinc oxide and hematite nanopowders. Field emission scanning electron microscopy transmission microscopy, X‐ray diffraction, photoelectron spectroscopy Raman confirmed the formation zinc‐ferrite with a mixed spinel structure small amounts remaining as impurities. Thick film paste formed screen printed on test interdigitated PdAg electrodes alumina substrate. Formation porous Hg porosimetry....
Nanocomposites of polyvinylidene fluoride/polymethyl methacrylate (PVDF/PMMA) blend and mechanically activated barium titanate (BaTiO3) particles were prepared by melt mixing. Modification filler means mechanical activation has a profound effect on the crystallization PVDF in matrix. Raman analysis showed that modified BaTiO3 particles, due to higher specific surfaces, induce, predominantly, electrically active β-phase PVDF, while initial micron size induce formation most common but...
