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.
