| titleOfInvention | Preparation method of copper/cuprous oxide coated paraffin microcapsule photothermal conversion phase change energy storage composite material |
| abstract | The invention discloses a method for preparing a copper/cuprous oxide coated paraffin microcapsule photo-thermal conversion phase change energy storage composite material by using a hydrothermal method, which comprises the following steps: mixing the sliced paraffin with oleylamine, and uniformly stirring at 65-85 ℃ to obtain a paraffin-oleylamine mixture; dissolving a reducing agent glucose and a copper source in deionized water, uniformly mixing, dropwise adding into the paraffin-oleylamine mixture, and uniformly stirring at 65-85 ℃ to obtain a reaction mixture; and placing the obtained reaction mixture in a high-pressure reaction kettle, reacting for 6-24 hours at 120-150 ℃, centrifuging the obtained reaction liquid, washing with deionized water, and drying for 12 hours at 50 ℃ to obtain the copper/cuprous oxide coated paraffin photo-thermal conversion phase change energy storage microcapsule. The preparation method is simple and low in cost, and the prepared microcapsule has uniform particle size smaller than 3 microns, good heat conduction performance and excellent light absorption performance by wrapping the paraffin with the copper with high heat conduction coefficient and the cuprous oxide with high light absorption performance. |
