摘要：
BaTiO3 (BT) nanoparticles with three kinds of diameters were synthesized by alkoxide route and then dispersed into a thermoplastic polyvinylidene fluoride (PVDF) and a thermoset polyimide (PI)) to fabricate the BT/PVDF and the BT/PI nanocomposite films. Effects of nanoparticle size and polymer matrix on the dielectric properties were studied by two different measurement procedures at frequencies from 10-2Hz to 106Hz. A significant discrepancy of dielectric behaviors between the BT/PVDF films and the BT/PI films was found. The roles of nanoparti...
