Preparation And Characterization Of Polyimide/Inorganic Composite Films As Solid Dielectrics

Considerable demand for solid thin-film dielectrics with high dielectric constants for use in the fabrication of capacitors has been observed. In this study, polyimide/inorganic composite films were prepared by incorporating different type of inorganic materials; Al2O3, BaTiO3, TiO2 and ZrO2, into p...

description	Considerable demand for solid thin-film dielectrics with high dielectric constants for use in the fabrication of capacitors has been observed. In this study, polyimide/inorganic composite films were prepared by incorporating different type of inorganic materials; Al2O3, BaTiO3, TiO2 and ZrO2, into polyimide (PI) derived from PMDA and ODA monomers via ultrasonication method. Chemical structure, morphology, dielectric and thermal properties were investigated by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), LCR meter and thermal gravimetric analysis (TGA). FTIR spectra showed complete imidization, and all characteristic peaks of the imide groups are observed in PI/inorganic composite films.
