摘要：
A high dielectric constant polymer composite system is presented. The new composite uses a high dielectric constant cyanoresin polymer filled with ferroelectric ceramics, such as BaTiO3 powder. While dielectric constant of the polymer is 21 at 1 kHz, the dielectric constant of the composite is over 130 at the BaTiO3 volume fraction of 51%, which is the highest dielectric constant reported so far for the polymer composite materials based on BaTiO3 filler. Frequency and temperature dependence of the dielectric constant of the composites are reported.
