Perovskite nanoparticle‐based nanocomposite thin films composed of oleic acid‐stabilized BaTiO 3 nanoparticles and poly(acrylic acid) are prepared by S.‐W. Kim, J. Cho, and team on page 6262 using ligand exchange layer‐by‐layer assembly in organic media. The resultant nanocomposite films with high dielectric constant and low leakage current exhibit ferroelectric and piezoelectric properties that could be exactly controlled by the bilayer number, the type of inserted polymer, and the nanoparticle size.
