The leakage‐prone disadvantage of pure phase change materials (PCMs) has hampered their practical application, and the encapsulation technology of PCMs has been favored for its ability to mitigate leakage. Combining large solar reserves with energy storage technology can increase the utilization of renewable energy and broaden the application of microencapsulated phase change materials (MEPCMs) in the field of solar energy. First, the fabrication technologies of MEPCMs, which include physical, chemical, and physical–chemical methods, have been comprehensively elaborated in this article. Second, the characteristics of different methods are also summarized. Then, the influences of MEPCMs properties on their thermal storage capacity have been clarified. This work shows the supercooling, phase separation, mechanical properties, encapsulation efficiency, and photothermal conversion performance of MEPCMs. Modification of MEPCMs by metal materials and their oxides, carbon, and semiconductor materials to improve the light absorption capacity. In addition, two‐dimensional materials such as MXene have been widely used to improve the photothermal properties of MEPCMs. Finally, the applications of MEPCMs in the construction, slurry, textile, and food industries are discussed. This work can provide some useful guidance for the optimization strategies of the photothermal conversion performance and practical applications of MEPCMs.

The influence of surfactants on polymer nanocomposites has revealed noteworthy performance in the properties of mechanical, thermal, optical and electrical. Incorporating graphene filler with small wt. (%) into polymer, matrices demonstrate enhancement in properties and avoid flocculation of graphene particles. In this report, we have comprehensively examined various methodologies for synthesizing surfactant‐modified graphene and subsequently incorporating it into polymer matrices. Our review provides a consolidated overview of these approaches. Parameters required for the dispersion of nanofiller graphene are also emphasized. Surfactant‐modified graphene poured into polymer composites is preferred for applications in the domain of electrical, sensing technology, and high elevated temperature regions. Prospects and challenges required for the functionalized graphene modifications for polymer‐graphene nanofillers are exhibited.This article is protected by copyright. All rights reserved

Thermal energy storage (TES) is vital to the absorption and release of plenty of external heat for various applications. For such storage, phase change material (PCM) has been considered as a sustainable energy material that can be integrated into a power generator. However, pure PCM has a leakage problem during the phase transition process, and we should fabricate a form stable PCM composite using some supporting materials. To prevent the leakage problem during the phase transition process, two different methods, microencapsulation and 3D porous infiltration, were used to fabricate PCM composites in this work. It was found that both microsphere and 3D porous aerogel supported PCM composites maintained their initial solid state without any leakage during the melting process. Compared with the microencapsulated PCM composite, the 3D porous aerogel supported PCM exhibited a relatively high weight fraction of working material due to its high porosity. In addition, the cross-linked graphene aerogel (GCA) could reduce volume shrinkage effectively during the infiltration process, and the GCA supported PCM composite kept a high latent heat (∆H) and form stability.
