Abstract

The invention discloses an azobenzene side chain polymer energy storage material and a preparation method thereof, wherein polyhydroxy azobenzene as a side chain is linked to the main chain of norbornene anhydride, and the storage and the release of polymer energy are realized through intermolecular hydrogen bonding force and cis-trans isomerism of azobenzene. According to the invention, synthesized azobenzene is grafted to norbornene anhydride, and then the target polymer is obtained through ring-opening ectopic polymerization; the obtained azobenzene side chain-containing polymer material has substantially improved energy density and substantially improved half-life period compared with the common azobenzene molecules, and has good plasticity compared with the azobenzene-graphene material; and the new method is provided for solar energy utilization, and the application range of azobenzene polymers is widened.

Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to a plastic azobenzene polymer energy storage material and a preparation method thereof, which has broad application prospects in the field of solar energy storage. Background technique [0002] With the rapid development of the world economy, the rapid improvement of science and technology, the demand for existing energy is also increasing, such as coal, oil, natural gas and other fossil resources. However, these resources are increasingly scarce, and human beings are exploiting these resources. Many environmental problems, such as the greenhouse effect, smog and other problems, have caused serious threats to the good life of human beings and the sustainable development of society. Therefore, the development and utilization of green new energy is imminent. [0003] Solar energy is a kind of clean natural renewable energy, inexhaustible and inexhaustible. The deve...
