Abstract
This study examines the use of a PMMA-mediated assembly of BaTiO 3 nanoparticles directly onto Cu electrodes under an electric field. The compatibility of the interface between BaTiO3 nanoparticles and PMMA in a mixed organic solvent system enables the homogeneous dispersion of nanoparticles in a solid polymer matrix. This results in the effective packing of particles, which is desirable from the point of view of achieving a high dielectric constant in the composite. In this study, three-phase Al/BaTiO 3/PMMA nanocomposite films from stable colloidal suspensions containing aluminium nitrate salts were also designed using an electrodeposition process. The simultaneous formation of Al metallic inclusions in the BaTiO 3 nanoparticles in the PMMA matrix significantly improved the dielectric constant of nanocomposite films.
