Abstract

The development of high-k composites based on CaCu3Ti4O12 (CCTO) ceramic powder is reported. The CCTO ceramic powders were prepared by traditional sintering method and were milled with a relative uniform size. Based on solution casting method, the composite using P(VDF-TrFE) copolymer as matrix and CCTO powders as filler were prepared and its dielectric response were characterized. The dielectric properties of the 0¿3 composite with micro-size and nano-size CCTO particle, as well as different polymer matrixes were determined. The 0¿3 composites exhibit a very high dielectric constant, more than 1700 at 1 kHz at room temperature after surface modification.
