Abstract
The development of shape-stabilized phase change materials (ssPCMs) is growing dynamically, and much research is being carried out in this field. This paper presents the results of the studies on the properties of PCM (paraffin wax) stabilized by methyltrimethoxysilane (MTMS)-based aerogels. Two methods of PCM stabilizing were studied: “dry” and “wet,” utilizing MTMS-based aerogels with six different morphologies. Then, the characteristics of the obtained materials were investigated. The aerogels of nanoporous, co-continuous, and macroporous structures were obtained. The results show that the ssPCMs possess hydrophobic properties, a high gravimetric loading of about 85 %, and volumetric shrinkage of about 20–29 % and 12–23 % for most samples obtained via dry and wet methods, respectively. The prepared ssPCMs show slight leakage in the air and water. The mass loss of PCM in the air environment does not exceed 1 % after eight thermal cycles, while it is no more than 10 % in the water. Furthermore, the leakage is observed in the first two cycles, ultimately leading to stable ssPCM. The samples are characterized by an excellent latent heat of fusion, which lies in the range of 105–163 J·g-1 (compared to 173 J·g-1 for pure paraffin wax). Also, no deterioration of the thermal conductivity of ssPCM samples was observed, which is 0.226–0.234 W∙m-1∙K-1 for ssPCMs and 0.248 W∙m-1∙K-1 for pure PCM. The data collected from this research suggest that the proposed methods of PCMs stabilization and prepared samples possess desirable properties and could be used in many areas regarding thermal energy storage.
