摘要
To promote the recycling of industrial waste and produce ultra-low carbon energy storage materials with low-energy consumption this work innovatively proposes to capture carbon dioxide using the mixture made of 70 wt.% desulphurization gypsum and 30 wt.% carbide slag via a aqueous solution method, and the carbonized mixture used as skeleton material to prepare phase-change composites via cold pression & hot sintering method, and then thermal property, mechanical property and chemical compatibility are investigated. Results show that the carbon capture rate of the skeleton material can reach up to 10.6% at room temperature and can encapsulate the PCM (NaNO3) intact. C-PCC3 has good thermal stability and can undergo 2058 heating/cooling cycles. Compared with the PCC3 (absent carbon capture), the C-PCC3 exhibited a notable enhancement in thermal conductivity by 2.7%. Nevertheless, there was a decrease in mechanical strength from 134.1 MPa to 44.9 MPa, and a reduction in thermal energy storage density from 483.2 J/g to 459.3 J/g. Based on both macroscopic properties and microscopic morphology, the phase change composite materials fabricated in this work exhibit excellent comprehensive property.
