Poly(amic acid) Treatment on BaTiO₃ and Effect on the Dielectric Properties of BaTiO₃/Polyimide Composites

Abstract:

We first modify the surfaces of BaTiO3 by hydrogen peroxide to induce hydoxyl groups that will be further reacted with a coupling agent. Then, with a silane coupling agent, we induce the amino group on the surface of particles. Modified BaTiO3 particles with the PI precursor (poly(amic acid)) are able to obtain poly(amic acid)-wrapped BaTiO3 particles. By employing this approach, higher dielectric value is obtained for the composite comprised of PI and PAA-wrapped BaTiO3 particles.
