Based on solution casting method, a ceramic [CaCu3Ti4O12 (CCTO)]-Polymer [P(VDF-TrFE)] composite with flexibility has been synthesized and its dielectric response has been studied. The CCTO ceramic powders were prepared by traditional sintering method and were milled with a relative uniform size. The dielectric properties of these films with micro-size and nano-size CCTO particle, as well as different polymer matrixes were determined. The process was optimized by hot pressing and surface modification to achieve high dielectric constant. A dielectric constant about 175 for one layer composite with high flexibility using silane coupling agent was obtained at 1 kHz at room temperature.
