摘要
Dielectric composites made using P(VDF-CTFE)88/12 mol%as polymer matrix and both micro-sized and nano-sized CaCu3Ti4O12(CCTO)particles as filler are developed.These composites exhibit high dielectric constant with a small dielectric loss.More importantly,it is found that the dielectric constant of these composites is almost independent of temperature from 25℃to 125℃.Comparing the composites made using micro-sized CCTO particles,the composites made using nano-sized CCTO particles exhibit a smaller dielectric loss.The dielectric properties of these composites indicate that the nano-sized CCTO particles have a smaller dielectric constant than the micro-sized CCTO particles.
