Preparation, Characterization and Dielectric Properties of BT/PI Film

Abstract:

By using mixture solution method, Barium titanate/polyimide(BT/PI) composite film was prepared. Influence of different size and filling quantity of BT particles were investigated. The microstructure and properties of the products were characterized by scanning electron microscopy, X-ray diffraction and other analysis methods. The results show that when BT nanoparticles are used, the BT/PI film has better comprehensive performance. As the filling quantity of BT particles increases, the dielectric constant and dielectric loss of BT/PI composite film increase, and the dielectric strength is reduced.
