1. Estudo das propriedades de armazenamento óptico e grades de relevo em poliuretano derivado de azo-benzeno / Information optically storage and relief gratings study in material derivative of azo-benzene polyrethane
Polymers containing azobenzenic groups have been studied due to their applications on non-linear optics, surface relief gratings (SRG) and photoinduced anisotropy for optical storage. The reversal photoisomerization trans-cis-trans property of the azo group induces a molecular reorientation. In this work, cast films of na azobenzene derivative, the polyureth
