RETRACTED: Preparation and dielectric properties of BaTiO3/epoxy nanocomposites for embedded capacitor application (Retracted article. See vol. 115, pg. 87, 2015)

Incorporating the inorganic particles into polymer have opened up novel opportunities to prepare the dielectric materials applied in embedded capacitors. In this work, the barium titanate (BaTiO3)/epoxy nanocomposites with excellent dielectric properties were fabricated. The embedded capacitors with three-layer sandwich structure containing the BaTiO3/epoxy nanocomposites as dielectric layer and copper foil as electrodes were prepared through lamination process. This method could ensure uniformity of capacitor paste in the structure, resulting in improved dielectric properties. The capacitors exhibit high dielectric permittivity (epsilon = 20), low dielectric loss (0.01) at 10(3) Hz from 40 degrees C to 100 degrees C and high breakdown strength (24 kV/mm). These results demonstrate that the BaTiO3/epoxy nanocomposites have potential for high-performance embedded capacitors in field of microelectronics. (C) 2014 Elsevier Ltd. All rights reserved.
