Abstract

Azo-polymeric materials present in the last decade a great interest due to their applications. Our materials are based on polysiloxanic chains, modified with different azo-benzenic groups. This new class of hybrid polymer (organic/inorganic) gives a large potential of applications in biology, chemistry, sensors, microelectronics etc. Due to photo-chromic properties of the azo-polymers it is possible to apply two kinds of techniques for surface relief gratings (SRG) generation, necessary for using the polymers in enumerated applications: continuous or pulsed light irradiation. Our work was focused on SRG generation on azo-polymers by pulsed light irradiation, with a Lloyd interferometric set-up. The resulting structures were analyzed, from optical point of view, by three methods: white light interferometry (WLI), optical microscopy and diffraction efficiency. All determination has been done in correlations with the irradiation parameters: fluence and number of pulses. We can say that the pulsed radiation interferometric patterning of azo-polysiloxanes is an efficacy and controllable technology to obtain surface relief gratings very necessary for the biological applications (cell culture) and optical methods analyses are useful for rapid determinations.
