Abstract:

A nonliquid crystal azobenzene polymer was prepared. The obtained films exhibit fast bending response at room temperature, which can improve the efficiency of the transformation of energy from light to mechanical energy. The surface structure of the relief gratings was investigated by atomic force microscopy. The depth of surface relief in a typical case is found to be around 94 nm. The product structures were characterize by UV light, 1H NMR, AFM and Fourier transform infrared spectrum.

Key words: Nonliquid crystal; Azobenzene polymer; Photoresponse; Surface relief gratings
