Problems solved by technology

[0005] In conclusion, there is no report on the preparation of phase-change composite energy storage materials using tubular conjugated microporous polymers as carriers, and the use of tubular conjugated microporous polymers as carriers to prepare phase-change composite energy storage materials greatly improves the phase change performance. The heat storage performance of variable composite energy storage materials also reduces the leakage rate of phase change materials, which is beneficial to energy storage and sustainable development

Description

technical field [0001] The invention relates to the preparation technology of a conjugated microporous polymer-based phase-change composite energy storage material. Background technique [0002] Today, due to the increase in population and the continuous development of industrial scale, people's energy consumption is increasing day by day; but at the same time, non-renewable energy sources such as fossil energy mainly composed of coal and oil are becoming increasingly exhausted, resulting in an increasingly tight supply of energy. Huge energy consumption not only causes energy shortage and serious environmental problems, but also seriously threatens the sustainable development of human beings. Therefore, solving the energy crisis faced by mankind has become a very important issue. [0003] Phase change materials are materials that can store and release latent heat to adjust the temperature of the environment when the phase changes from solid to liquid or from liquid to soli...
