Laser-induced formation of “craters” and “hills” in azobenzene-containing polymethacrylate films
Original language description
Functional organic macromolecular materials with an ability to change their topology in response to external contactless stimuli, like light irradiation, attracts considerable attention. This work is devoted to contactless control of the surface topology and formation of the surface features in the amorphousized and liquid crystalline films of two azobenzene-containing polymers. The investigated polymers are based on methacrylate polymeric backbone and side-chains containing the azobenzene chromophores with two lateral methyl substituents in ortho-positions. Irradiation of the polymethacrylate films by focused polarized light of green (532 nm) and red (633 nm) lasers induces a specific photodeformation of the films surface. In the case of the green light formation of the “craters” having anisotropic borders was found, whereas for the red light highly asymmetric “hills” were observed. The possible mechanisms of the surface topology feature and formation are discussed.n
