| Abstract |
In this work, nano Ag-deposited (In3+, Nb5+) co-doped TiO2 (Ag-INTO) hybrid particles are prepared by a seedmediated
growing process by a redox reaction between silver nitrate and ethylene glycol. Ag-INTO hybrid
particles are used as fillers for fabricating flexible polymeric composites to enhance dielectric permittivity and
retain low dielectric loss tangent of polyvinylidene fluoride (PVDF). Nano-Ag particles deposited on INTO
surface are revealed by a transmission electron microscopy. Ag-INTO/PVDF composites are fabricated by
conventional mixed powder and hot pressing methods. The dielectric properties as functions of frequency and
temperature were investigated. Enhanced dielectric permittivity of »102 and low loss tangent of £0.1 in a low
frequency range are successfully achieved by optimizing loading content of Ag-INTO filler. The discrete
growth of Ag nanoparticles on INTO ceramic particles efficiently prevented the continuous contact between Ag
metallic particles in the PVDF matrix. This can suppress the formation of the conducting path in the composite,
resulting in a low loss tangent and conductivity [1]. |
