preparation example Construction

[0018] The present invention designs the preparation method of above-mentioned azobenzene polymer, and described method reaction formula is illustrated as follows:

[0019]

Embodiment 1

[0021] 1) Dissolve 3g of 3,5-dicarboxylic acid aniline and 1.52g of sodium nitrite in deionized water, add 48ml of 1mol / l hydrochloric acid under ice bath conditions, carry out diazotization for half an hour, then add to 2.5g of 3,5- In the dimethoxyphenol solution, keep the pH between 5-7, and react for 8 hours. After the reaction is over, adjust the pH to about 3, filter with suction to obtain the crude product of the filter cake, and use the obtained crude product with deionized water and anhydrous After washing with water and ethanol for several times, 5 μm silica gel was used as the stationary phase, and ethyl acetate / n-hexane was used as the eluent for chromatographic separation. The obtained fraction was distilled under reduced pressure and dried under vacuum to obtain AZO 3g.

[0022] 2) Dissolve 2g of cis-5-norbornene-exo-2,3-dicarboxylic anhydride and 1.6g of 6-aminocaproic acid in 20ml of toluene solution, add 0.1ml of triethylamine dropwise, and heat up to React a...

Abstract

The invention relates to an azobenzene polymer energy storage material in which azobenzene is grafted to the side chain of polynorbornene. The structure of the material is shown in the description.

Description

technical field [0001] The invention relates to a design and preparation method of a spinnable azobenzene polymer energy storage material, which has broad application prospects in the field of solar energy storage and belongs to the field of composite functional materials. Background technique [0002] Energy is closely related to the development of human society, and every energy revolution will bring huge changes to society, science, technology, economy, politics, etc. At present, traditional energy such as coal, oil and natural gas is still the most used in the world. The total amount of this type of energy is limited, and the process of exploitation and use has brought ecological crisis, environmental damage, greenhouse effect and other problems. Therefore, the development and utilization of new environmentally friendly alternative energy sources is a major problem that needs to be solved urgently in the world. At present, new energy sources that have been developed and...
