摘要

In the present study, the microstructure and dielectric properties of composites comprising Polyimide (PI) and CaCu3Ti4O12 (CCTO) or CaCu 3Ti3.95Zr0.05O12 (CCTZO) particles have been investigated. CCTO and CCTZO were employed separately and investigated comparatively. The effective dielectric constant of the composite containing 40vol.% CCTZO filler is over 50 at 40°C (102 Hz), which is substantially higher than that of the composite containing CCTO. For the composite containing 40vol.% CCTZO, the dielectric constant and the conductivity increases sharply with increasing temperature. The mechanism of high dielectric constant was investigated finally.
