Russia and Czech Republic have created new photopolymers
Researchers from the Moscow State University (MSU) and the Institute of Physics (Prague) synthesized liquid crystalline polymers. These polymers change their properties under the polarized light influence. In perspective, similar materials may be used for memory devices.
Photopolymers can combine the optical properties of liquid crystals and the polymers mechanical properties. «Polymers can quickly change the orientation of the molecules under the external fields influence and simultaneously able to form coatings, films and parts of complex shapes», — reported the University press service.
Polymers composed of macromolecules. These molecules are linked with organic photosensitive substances called azobenzene moieties. If a light stream hits the material, the groups begin to rebuild. In particular, they change the angle relative to the light ray.
The Institute of Physics of Materials of the Academy of Sciences of the Czech Republic (IPM ASCR) participated in the creation of technology for the monomer synthesis. Then this technology was used as the basis for liquid crystal polymers.
Although the cost of polymers synthesized by researchers does not allow them to be used for commercial purposes, scientists believe that in the future such materials can be used to record information. «Photopolymers are sensitive to various external influences and can be used for storage, recording and transfer of information in optical devices», — explained Alexey Bobrovsky, the professor of the Russian Academy of Sciences and representative of MSU.
The results of the study are published in Macromolecular chemistry and physics.
