Embodiment 1

[0105] Add 4# compound to the toluene solution containing 20# compound obtained in step (2), heat up to 90°C, and react for 12h, wherein the molar ratio of 20# compound to 4# compound is 1:1, to obtain a polyether type Organic polymer shape-fixing phase change support material; adding hexadecanol organic solid-liquid phase change energy storage material under mechanical stirring conditions, wherein the hexadecanol organic solid-liquid phase change energy storage material and the obtained polyether-type organic polymer shape-changing phase The mass ratio of the variable support material was 63.8:36.2, mixed for 2 hours, evaporated the solvent, and dried to obtain an organic shape-setting phase change energy storage material (abbreviated as 63.8% cetyl alcohol / polyurethane organic shape-setting phase change energy storage material). From the infrared spectrum of the material (attached figure 1 ), it can be seen that no new characteristic peaks appear in the infrared (curve b) of...

Embodiment 2-8

[0110] The 21-27# compound is used instead of the 20# compound in Example 1 to react with the 4# compound to obtain the corresponding organic shape-setting phase change energy storage material, and other conditions are the same as those of Example 1.

Embodiment 9

Abstract

The invention relates to an organic phase stabilization, phase transition and energy storage material and a preparation method thereof. The organic phase stabilization, phase transition and energy storage material comprises 30-90wt% of an organic solid-liquid phase transition and energy storage material and 10-70wt% of an organic polymeric phase stabilization and phase transition supporting material. The organic solid-liquid phase transition and energy storage material is introduced into the polymeric phase stabilization and phase transition supporting material in order to make the organic phase stabilization, phase transition and energy storage material have good energy storage performance, adjustable phase transition temperature and high phase transition enthalpy; and when B in the polymeric phase stabilization and phase transition supporting material is an azo structure, anthraquinone, naphthalene amide and pyrene amide, the organic phase stabilization, phase transition and energy storage material can absorb visible light, and realizes photo-thermal transition and storage. The organic phase stabilization, phase transition and energy storage material has the advantages of simple synthesis process, convenient application, and wide application prospect.

Description

technical field [0001] The invention relates to an organic shape-setting phase-change energy storage material and a preparation method thereof. Background technique [0002] Phase change energy storage materials absorb or release a large amount of heat through physical phase transition (solid-liquid, liquid-gas, etc.) to achieve energy storage and utilization, which is one of the effective ways to improve the efficiency of thermal energy utilization. It has the advantages of strong energy and ability, and can effectively alleviate the conflict between space and time imbalance in energy supply. [0003] In order to realize the shape stability of the phase change material before and after the phase change and avoid the problem of additional packaging for the solid-liquid phase change material, relevant researchers have obtained the shape-set phase change heat storage material by means of chemical reaction and physical doping, such as Qinghao Meng et al. Human use of diphenylm...
