Fabrication of polycondensed multilayer thin films by a self-assembly method

UV-vis and quartz crystal microbalance (QCM) measurements were used to monitor the layer-by-layer deposition process. FT-IR reflection absorption spectroscopy (FT-IR-RAS) was also carried out in order to confirm the polycondensation of monomers. These results indicated that dicarboxylic acid and diamines were alternately deposited and polymerized with condensing agents on nano-scale. In addition, polydiacetylene network was successfully incorporated in DDyDA system by γ-irradiation due to the high ordered structure.
