Advanced calcium copper titanate/polyimide functional hybrid films with high dielectric permittivity

A study was conducted to investigate advanced calcium copper titanate (CCTO) and polyimide (PI) functional hybrid films with high dielectric permittivity. The CCTO and PI hybrid films showed better dielectric properties as the in situ polymerization process drove the CCTO fillers into the PI homogeneously. The giant dielectric permittivity originated from the internal boundary layer capacitance. The semiconducting characteristic of the CCTO fillers induced the resultant high dielectric permittivity, the resultant high dielectric permittivity, and PI hybrid films. It was assumed that the giant dielectric permittivity of CCTO was to complement and increase the overall dielectric permittivity of the CCTO and PI hybrid films. The study also revealed an advanced high-K CCTO and PI functional hybrid film that displayed other significant properties.
