Research progress on preparation, characterization, and application of nanoparticle‐based microencapsulated phase change materials

Abstract

Summary As an energy storage material, microencapsulated phase change materials (MPCMs) have become a research hotspot in recent years due to their unique thermophysical properties. However, this material usually has limitations in terms of its performance, such as low encapsulation efficiency, leakage during phase change, poor cycle stability, and high degree of supercooling. To solve these problems, nanoparticle as‐modified material to improve the performance of MPCMs has attracted the attention of both domestic and overseas scholars. This paper aims to review the research progress of MPCMs modified by nanoparticle from three aspects: preparation, performance, and application. In this paper, the preparation method and principle of nanoparticles used for the modification of MPCMs are first introduced. Then, based on different properties (mechanical properties, thermal conductivity, thermal stability, and supercooling), the research works of nanoparticle‐modified MPCMs in recent years are reviewed. Finally, the practical applications of nanocomposite MPCM in the field of slurry, building, asphalt pavement, and battery thermal management are reported.

Fabrication of Organic Shape-stabilized Phase Change Material and Its Energy Storage Applications

“…Same as the thermal conductivity, leakage-proof property is mainly related to the OPCM, filler and matrix as well as the manufacture method, on condition all of the aforementioned factors significantly influence the interactions between each component. [19] Therefore, the performance of SSPCMs are determined by four factors: OPCM, skeleton, filler and fabrication method which are necessary to be comprehensively considered.…”

Investigation of the effectiveness of microencapsulated phase change materials for bitumen rheology

“…1 Asphalt mixture, which is sensitive to extreme weather conditions, is exposed to different temperature effects during the whole service life. 2,3 The fatigue, aging, and rutting properties of bitumen have a considerable influence on the performance of the road pavement since asphalt mixture is sensitive to high temperature. 4 It has been reported in many studies that asphalt performance is affected by environmental factors, especially temperature.…”

Thermophysical properties and thermal performance evaluation of multiwalled carbon nanotube‐based organic phase change materials using T‐History method

“…Results revealed that the average and peak overall photovoltaic thermal efficiencies had been improved, and also the electrical efficiency of the photovoltaic thermal was higher than photovoltaic. Lin et al 25 used microencapsulated phase change materials as an energy storage material. It solved the problems of leakage during phase change, poor cycle stability, low encapsulation efficiency, and a high degree of supercooling.…”
