Abstract

Current research efforts toward achieving ceramic/polymer composites which fulfill the balance between sufficiently high dielectric constant (ε) and low dielectric loss (tanδ) are presented. In this paper, ceramic/polymer composite films made of CaCu3Ti4O12 (CCTO) powder as filler, which is modified by silane coupling agent vinyltrimethoxysilane (A-171), and polyvinylidene fluoride (PVDF) copolymer as matrix were prepared by solution casting method. The morphology and dielectric properties (DP) were studied by transmission electron microscopy (TEM) and impedance analyzer. The effect of pH and ethanol concentration on the dielectric properties of A-171@CCTO/PVDF were studied. The results show that constant could reach 54.17 and loss 0.05 when mass fraction of A-171 is 0.4% at 1 kHz. pH=4 and using anhydrous ethanol are the optimal conditions.
