Nanocomposites of Ferroelectric Polymers with TiO2 Nanoparticles Exhibiting Significantly Enhanced Electrical Energy Density

Novel dielectric nanocomposites composed of ferroelectric polymers and surface-functionalized TiO2 nanoparticles with comparable dielectric permittivities and homogeneous nanoparticle dispersions are prepared and characterized. Enhancements in electric displacement and energy density at high electric fields are demonstrated.
