BACKGROUND: Many studies have been reported on the photo-fabrication of surface relief gratings (SRG) by interfering two laser beams of appropriate polarization in an azo-polymer film. However, there are few reports in the literature concerning the electro-fabrication of SRG on such kind of polymer films. The goal of this work was the electro-patterning of an azobenzene containing epoxy thermoplastic film. relief gratings (SRG) by interfering two laser beams of appropriate polarization in an azo-polymer film.

RESULTS: An epoxy based polymer functionalized with an azo-chromophore was synthesized and characterized by thermal analysis. The reversible optical storage properties and photo-induced dichroism were studied. Surface relief gratings were fabricated on a film of the synthesized azobenzene containing polymer using contact mode current-sensing atomic force microscopy (AFM) which locally applied an electric field that aligned the azobenzene moeties. synthesized and characterized by thermal analysis.

CONCLUSION: The anisotropic mass transport of the azo-polymer film was observed after applying the electric field. Additionally, the effect of the reliefs formation in the polymeric film surface was investigated by means of atomic force microscopy and electrostatic force microscopy (EFM). after applying the electric field.
