New layered 1:1 mixed Ba(2+)/Ti(4+) metal phosphonates, BaTi(O(3)PC(6)H(5))(3) and SrTi(O(3)PC(6)H(5))(3), have been prepared via a hydrothermal route, in which mixed metal oxides, BaTiO(3) and SrTiO(3), were reacted with phenyl phosphonic acid. The mixed-metal phosphonates were combined with polystyrene (PS) via a solution route and cast as thin films for dielectric permittivity measurements. The composites exhibit an enhancement in the dielectric permittivity as a function of weight loading relative to the parent mixed metal oxide-PS composites.
