Synthesis of BaTiO nanoparticles as shape modified filler for high dielectric constant ceramic-polymer composite.

Coral-like structured barium titanate (BaTiO) nanoparticles were synthesized as filler for a high dielectric elastomer. The nanoparticle size, and shape, and the reactivity of the synthesis were modified according to temperature, time, pH, and precursor materials. Dielectric properties of poly(dimethylsiloxane) (PDMS) composites were estimated by volume fractions of BaTiO of 5, 10, and 15 vol% for both sphere and coral-like shapes.
