Resumen:
In this work, 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 also studied. Surface relief gratings (SRGs) were fabricated on a film of the synthesized azobenzene containing polymer using a contact mode current-sensing atomic force microscopy which locally applied an electric field that aligned the azobenzene moeties. The anisotropic mass transport of the azo-polymer film was observed after applying the electric field. Additionally, it was investigated the effect of the reliefs formation in the polymeric film surface by means of atomic force microscopy (AFM) and electrostatic force microscopy (EFM).
