摘要（英）：

The invention discloses a linear di-branched azobenzene polymer as well as a preparation method and application thereof. Di-branched azobenzene is grafted onto the side chain of polymethacrylic acid in a chemical bond way, so that the linear di-branched azobenzene polymer is obtained; the linear di-branched azobenzene polymer has a number-average molecular weight of 18,000-220,000, an energy density of 130-150Wh/Kg and a half-life of 850-950h. The preparation method of the linear di-branched azobenzene polymer comprises the following steps: (1) carrying out amino protection; (2) preparing amino-protected di-branched azobenzene; (3) preparing the di-branched azobenzene polymer. The di-branched azobenzene polymer provided by the invention is high in molecular weight and flexibility and goodin film-forming property, thus being convenient to popularize and apply.
