| 摘要 | As a type of promising phase-change materials, sugar alcohols have a great potential for thermal energy storage due to their high energy-storage density. However, the intermolecular hydrogen bonding of sugar alcohols results in high supercooling and low thermal-energy-release efficiency. In this paper, we proposed a strategy for fabricating biomass-derived carbonaceous aerogel (BDCA)/mannitol phase-change composites by a simple vacuum impregnation method to depress supercooling and enhance the thermal-energy-release efficiency. The BDCA derived from a biomass waste, watermelon rind, exhibits unique features like light weight, abundant porosity, and rich oxygen groups in nature and can be used as an ideal supporting material for the fabrication of shape-stabilized phase-change composites. The BDCA/mannitol phase-change composites developed by this work not only possess a high thermal energy capacity of over 280 J/g but also exhibit reduced supercooling, improved thermal conductivity, good thermal stability, superior shape stability, and excellent thermal-cycle stability. More importantly, the BDCA/mannitol phase-change composites present extremely high thermal-energy-release efficiency of over 95% at the BDCA loading higher than 9 wt %. This study offers a promising methodology for the development of sugar-alcohol-based phase-change composites with a high thermal-energy-storage density and high energy-release efficiency for medium-temperature thermal-energy-storage applications. |
