Flexible　PVC/BT　(Polyvinyl　chloride/Barium　Titanate)　composite　thick　films　with　(0-30%)　volume　fractions　of　BaTiO3　were　fabricated　via　the　solution　casting　method.　The　effects　of　BaTiO3　filler　on　the　phase,　microstructure　and　dielectric　properties　of　composite　films　were　investigated.　The　XRD　results　revealed　that　BT　particles　are　embedded　in　the　PVC　matrix　with　no　chemical　reaction　taking　place　between　the　two　phases.　It　was　observed　that　the　glass　transition　temperature　of　PVC　had　increased　with　the　addition　of　BT.　The　frequency　dispersion　in　the　dielectric　constant　versus　temperature　curves　indicated　the　relaxor　nature　of　the　composites.　The　dielectric　constant　(epsilon(r))　measured　at　40　degrees　C,　increased　from　7.6　for　pure　PVC　to　16.1　for　30%　of　BaTiO3　content　in　PVC　polymer　matrix.　It　is　suggested　that　BaTiO3　ceramic　powder　enhanced　the　dielectric　properties　of　PVC　and　may　be　used　as　a　flexible　dielectric　material.
