Azobenzene photoisomerization composite material containing core-shell structure and preparation method of azobenzene photoisomerization composite material
According to the azobenzene photoisomerization composite material containing the core-shell structure and the preparation method of the azobenzene photoisomerization composite material, rapid ice melting is achieved through a rare earth material with the heat absorption performance, meanwhile, an azobenzene structure with photoisomerization transformation is utilized and grafted to the titanium dioxide coated core-shell structure, on one hand, the strength of the material is enhanced, and on the other hand, the performance of the azobenzene photoisomerization composite material is improved. On the other hand, the structure change of the azobenzene unit in the whole time period can be realized along with the intensity change of ultraviolet visible light in railway operation, so that an ice layer has stress change and is easier to peel off.
本发明提供了一种含核‑壳结构的偶氮苯光致异构复合材料及其制备方法，利用具有吸热性能的稀土材料实现快速融冰，同时利用了具有光致异构变换的偶氮苯结构，将其接枝在二氧化钛包覆的核壳结构上，一方面增强了材料的强度，保护稀土粒子不易脱落，另一方面随着铁路运行中紫外可见光的强弱变换，可以实现偶氮苯单元全时段的结构变化，使冰层出现应力变化从而更易剥落。
