The study of the morphology of PPy/nanoparticle composite material by scanning and transmission electron microscopies shows us that the gold nanoparticles can be stably coated on the surface of PPy. The Surface-enhanced Raman Scattering spectrum results indicated that the composite microtubes can be applied to hold and analyze trace molecules as signal-enhancing cuvettes for Raman spectroscopy.

POMs and deys are still maintained integrallty.AFM exhibits the films is even.The thickness of each layer is about 1.25nm. The AFM images reflect that there are some protuberances on the outer surface layer of the film, which due to the aggregates of spherical structure PMo12. Cyclic Voltammograms reflects the redox potentials of dye in multilayer shifts towards more positive values than pure dye multiplayer which may be explained by charge transfer from dye to POM. Fluorescence spectra show that polyoxometalates caused the fluorescence decay of dyes, which maybe used as fluorescence sensors.
