Barium titanate (BaTiO3) and silver (Ag) composite film with high dielectric constant was grown at room temperature by an aerosol deposition method. The dielectric constant increases by 0.5 times after adding Ag to the BaTiO3 matrix, compared with pure BaTiO3. The high dielectric constant can be attributed to the percolation effect of Ag inclusions in the BaTiO3 matrix. The Ag was present in the form of discrete layer in the BaTiO3 film. The dielectric properties of BaTiO 3-Ag were discussed in detail taking into account the changes in microstructures.
