摘要

通过在石蜡中添加氧化铝（Al₂O₃）、氧化钛（TiO₂）纳米粒子、碳纳米纤维（CNF）以及Al₂O₃+TiO₂和Al₂O₃+CNF组合体开展相变储热材料的热物性强化研究。通过实验研究添加单一颗粒和多元颗粒对石蜡热物性的影响。以Span80为表面活性剂,成功制备了不同浓度的纳米复合相变材料。采用差示扫描量热仪和瞬态热线法测定了样品的热物性。利用扫描电子显微镜和傅里叶变换红外光谱对制备样品的表面形貌和化学结构进行表征。研究结果表明,Al₂O₃、TiO₂和CNF纳米颗粒在相变材料中实现了均匀分散,未发生化学反应;随着Al₂O₃、TiO₂和CNF颗粒的加入,单一和多元纳米复合相变储热材料潜热略有降低。与纯石蜡相比,质量分数1.0%的Al₂O₃+CNF多元复合材料导热系数提高了36.79%,液相比热容提升32.07%。Al₂O₃和CNF组合对相变材料热物性具有协同强化效果。本文的研究可为持续推进太阳能储热容技术的利用提供参考。

Abstract

Paraffin waxes have great application potential in the field of low-temperature solar energy storage technology due to their wide phase transition temperature range, moderate latent heat and good chemical compatibility. In order to enhance the heat transfer/storage performance of paraffin wax, this paper gives thermophysical property enhancement study of nanocomposite phase change materials NCPCMs） dispersed by Al₂O₃, TiO₂ nanoparticles, carbon nano-fiber （CNF）, Al₂O₃+TiO₂ and Al₂O₃+CNF in paraffin. The effects of adding mono and hybrid particles on the thermophysical properties of paraffin are experimentally investigated. The samples of NCPCMs with different concentrations are successfully prepared with Span80 as surfactant. The differential scanning calorimeter and transient hot-wire method are used to measure the thermophysical properties of the samples. A scanning electron microscopy and a Fourier transform infrared spectroscopy are used to characterize the surface morphologies and chemical structures of the prepared samples. The results show that Al₂O_3, TiO₂ and CNF nanoparticles have uniformly dispersed in both mono and hybrid NCPCMs without any chemical reaction. The latent heat of paraffin decreases with the addition of Al₂O₃, TiO₂ and CNF nanoparticles in both mono and hybrid NCPCMs slightly. Compared with pure paraffin, the thermal conductivity of Al₂O₃+CNF composite with mass fraction of 1.0% increased by 36.79%, and the specific heat of liquid phase increased by 32.07%. As a conclusion, the hybrid nanoparticles of Al₂O₃+CNF shows significant potential for thermophysical property enhancement of phase change materials.
