Abstract

The fabrication of LbL (layer by layer) self-assembled thin films is attracting attention for various applications. Hence, the detailed characterization of these films is very vital. In this study, interaction between the conjugate/non-conjugated polyelectrolyte pairs, final film compositions and viscoelastic behavior of the LbL multilayer thin films are determined using the quartz crystal microbalance dissipation (QCM-D) technique. Firstly, anodic color changing polyaniline (PAni) based LbL films as electrodes are coated on flexible PET-ITO substrate and extensive characterizations are performed. Secondly, electrochemical characterization of these films in LiClO4/PC electrolyte is carried out. It is found from QCM-D and UV
