Paper Abstract

Piezoelectric thin films incorporating poly(sodium 4- styrenesolfonate)(PSS) and poly(diallyldi-methylammonium chloride)(PDDA) were 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 very important role in molecular alignment resulting in net polarization in the layer-by-layer structured ultrathin film, a process quite different from that used to form conventional piezoelectric films. Further study concerning the principles governing the novel ESA processing of piezoelectric films is on-going.
