제목 Dielectric Properties of Polyimide Composites Filled with BaTiO3Decorated Silver Nanoparticles by Reduction Method
초록 The dielectric properties of polyimide(PI) composites filled with BaTiO3(BT) decorated silver nanoparticles are investigated. BT is oxidized(COOH-BT) and then COOH-BT is decorated with silver nanoparticles(Ag-BT) by reduction method. After BT and Ag-BT are dispersed by poly (amic acid) and then distributed as a way to thermal and chemical reaction composite material was manufactured by filler contents. The difference of morphology of BT and Ag-BT is observed by high resolution transmission electron microscopy(HR-TEM). Dielectric properties of the composites according to frequency, the types of filler and the amounts of filler are investigated. PI/Ag-BT composites are shown higher permittivity and loss tangent than PI/BT composites.
