A very high dielectric constant polymer composite film system is presented. The new polymer composite film uses cyanoresin polymer filled with ferroelectric ceramics, such as BaTiO3 powder. While the dielectric constant of the cyanoresin polymer at 1 kHz is 21, the dielectric constant of the polymer composite film filled with 50 % BaTiO3 powder is over 133, which is the highest dielectric constant for the polymer composite materials. Frequency and temperature dependence of the dielectric constant of the polymer composite system are reported.
