Synthesis and Characterization of BaTiO₃ Particle/Polymer Hybrid from Metal-Organics

Abstract

BaTiO₃ nanoparticle/polymer hybrid was synthesized from metal-organics via in situ process. A BaTiO₃ precursor was synthesized from Ba metal, titanium isopropoxide and unsaturated ligand for polymerization. The precursor was polymerization and hydrolyzed yielding BaTiO₃ particle/polymer hybrid. The BaTiO₃ precursor and BaTiO₃ particle/polymer hybrid were characterized by FT-IR, H-NMR and XRD. Nanocrystalline BaTiO₃ particles were confirmed to be dispersed in the polymer matrix. The crystallinity and size of BaTiO₃ particles were dependent on the hydrolysis and polymerization condition. The dielectric properties of the hybrid were also measured.
