Thermal and electrical properties of nitrile‐containing polyimide/BaTiO<sub>3</sub> composite films
Abstract
<jats:title>Abstract</jats:title><jats:p>Polyimide composite films were prepared by mixing the BaTiO<jats:sub>3</jats:sub> particles into poly(amic acid) solution followed by film casting and thermal imidization under controlled temperature conditions. The poly(amic acid) was synthesized by solution polycondensation reaction of 4,4′‐oxydiphthalic anhydride with 2,6‐bis(4‐aminophenoxy)benzonitrile, using <jats:italic>N</jats:italic>‐methyl‐2‐pyrrolidone as solvent. The surface of BaTiO<jats:sub>3</jats:sub> particles was modified by treating with an aminosilane coupling agent, 3‐aminopropyltriethoxysilane. Fourier transform infrared spectroscopy, X‐ray diffraction and scanning electron microscopy were used to characterize the structure and properties of the composites. The influence of BaTiO<jats:sub>3</jats:sub> content on the composite film properties was evidenced. The films exhibited good thermal stability having the initial decomposition temperature above 520°C. They had stable dielectric properties over large intervals of temperature and frequency. The dielectric constant and the dielectric loss increased with the increase of BaTiO<jats:sub>3</jats:sub> content. The dynamic mechanical analysis and dielectric spectroscopy revealed subglass transitions γ and β. At higher temperature an α‐relaxation that corresponds to the glass transition and a conductivity process were evidenced. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers</jats:p>
