Photoinduced fabrication of complex surface relief structures on azobenzene functionalized polymers

Contactless, photoinitiated snap-through in azobenzene-functionalized polymers.

Photomechanical effects in polymeric materials and composites transduce light into mechanical work. The ability to control the intensity, polarization, placement, and duration of light irradiation is a distinctive and potentially useful tool to tailor the location, magnitude, and directionality of photogenerated mechanical work. Unfortunately, the work generated from photoresponsive materials i...

Birefringence Properties and Surface Relief Grating Formation on Methylacrylate Polymers with Photochromic Side Chains

We have studied light-induced birefringence (LIB) and surface relief grating (SRG) formation in the series of methylacrylate polymers. The effect of material structure such as length of photochromic side chain, glass transition temperature and molecular structure of azo units on LIB and SRG are studied. The optical formation of self-induced SRG on films of these materials is also presented.

Photoinduced Deformations in Azobenzene Polymer Films

This review is devoted to the microscopic mechanism behind photoinduced deformations in side-chain azobenzene polymers. We present the analysis of selected experiments that allows us to propose main criteria for a proper choice of the light induced force. Particularly, we provide convincing evidence that, contrary to a well-spread belief, light induced softening is a very weak accompanying effe...
