摘要：

A functional hybrid film with high dielectric permittivity and good thermal stability is obtained using calcium copper titanate as filler in a polyimide polymer matrix. The giant dielectric permittivity of the filler and its semiconducting characteristics impart good dielectric properties to the hybrid films. A dielectric permittivity high as 49 is achieved at a 40vol% filler concentration at 10(2) Hz.
