          摘要:

          摘要:隨著人們對環境保護的重視,太陽能的開發利用成為當前研究重點,而發展以相變材料(PCM)為基礎的潛熱儲存技術是提高太陽能開發利用的重要措施之一。以二維過渡金屬碳化物和/或碳氮化物(MXene)為支撐骨架,以棕櫚酸(PA)為相變材料,通過熔融共混法制備MXene復合材料(PA/MXene),并對不同Mxene添加量的復合材料進行了結構表征和熱性能分析。與純棕櫚酸相比,PA/MXene-20%〔MXene質量分數為20%(以PA/MXene復合材料的質量為基準)〕的吸光范圍從200-263.2 nm增加到200-679.3 nm,降解溫度提高了13%,導熱能力可增加到200%,光熱轉換效率達到84.5%,可實現太陽能光熱轉換、熱能儲存的一體化應用。

          Abstract:

          With the emphasis on environmental protection, the development and utilization of solar energy has become the focus of current research, and the development of latent heat storage technology based on phase change materials (PCM) is one of the important measures to improve the development and utilization of solar energy. In this paper, MXene composites (PA/MXene) were prepared by melt blending method using two-dimensional transition metal carbide and/or carbon nitride (MXene) as the support skeleton and palmitic acid (PA) as the phase change material, and the composites with different Mxene additions were structurally characterized and thermally characterized. Compared with pure palmitic acid, the light absorption range of PA/MXene-20% [MXene mass fraction of 20% (based on the mass of PA/MXene composite)] is increased from 200-263.2 nm to 200-679.3 nm, the degradation temperature is increased by 13%, the thermal conductivity can be increased to 200%, and the photothermal conversion efficiency reaches 84.5%, which can realize integrated application of solar photothermal conversion and thermal energy storage.
