Graphical Abstract

Thumbnail image of graphical abstract

Phosphonic acids act as robust surface modifiers on barium titanate (BT) nanoparticles (NPs) (see figure), affording homogeneous, high-volume-fraction composites of such NPs in polymeric hosts by simple solution processing. Pentafluorobenzyl phosphonic acid-modified BT nanocomposite films in poly(vinylidenefluoride-co-hexafluoropropylene) show large relative permittivities and unusually high dielectric breakdown strengths.
