dc.description.abstract | It is well known that light-induced multiple trans-cis-trans photoisomerizations of
azobenzene derivatives attached to various matrices (polymeric, liquid crystalline polymers) result in
polymer mass movement leading to generation of surface reliefs. The reliefs can be produced at small
as well as at large light intensities. When linearly polarized light is used in the process, directional
photo-induced molecular orientation of the azo molecules occurs, which leads to the generation of
optical anisotropy in the system, providing that thermal effects are negligible. On the other hand,
large reliefs are observed at relatively strong laser intensities when the optofluidization process is
particularly effective. In this article, we describe the competitive thermocapillary Marangoni effect of
polymer mass motion. We experimentally prove that the Marangoni effect occurs simultaneously
with the optofluidization process. It destroys the orientation of the azopolymer molecules and results
in cancelation of the photo-induced birefringence. Our experimental observations of polymer surface
topography with atomic force microscopy are supported by suitable modelings. | pl_PL |
