Abstract | Layer-by-layer self-assembly (L-b-L assembly) makes possible to obtain polyelectrolyte multilayers (PEMs) and one of the polyelectrolytes could be replaced by a dye molecule to obtain multilayers which may exhibit optical properties of great interest. On the other hand, μCp has become a routine technique for the preparation of micro- and nanostructured surfaces. In our development in progress of a surface engineering strategy to transfer J-Agg cyanine dyes onto surfaces by integrating L-b-L process and μCp, this contribution highlights how surface analysis imaging techniques can bring valuable information for the development of the process involving a double Multilayers Transfer Printing (MTP) with a Moiré effect. Key parameters sustaining image interpretation are difference in deposit thickness (optical microscopy, atomic force microscopy, scanning electron microscopy), in roughness (atomic force microscopy and scanning electron microscopy), in charge effect (scanning electron microscopy) and the chemical contrast between unprinted and printed areas (time-of-flight secondary ion mass spectrometry). |
