Peizoelectric ultrathin composite film comprised of PSS and PDDA was synthesized using the electrostatic self-assembly (ESA) process. The ESA processed PSS/PDDA film is a layer- by-layer laminated structure, which exhibits piezoelectric response directly, with a piezoelectric coefficient d33 = 6.0 pC/N and without poling treatment. It is assumed that the self-assembly process may play a role in molecular alignment resulting in net polarization in the layer-by- layer structured ultrathin film, a process quite different form that used for form conventional piezoelectric films.
