“…Compared with inorganic PCMs, organic PCMs are more applicable due to non-toxic and non-corrosive characteristics. 24,25 However, liquid leakage happens during the solid-liquid phase transition process in organic PCMs, [26][27][28][29] and this issue could be addressed by microencapsulation to realize convenient use of organic PCMs. Notably, dispersing microencapsulated PCMs into working uids (e.g., water, ethylene glycol, etc.)…”

“…However, some polymer‐based SSPCMs encounter several challenges such as leakage, thermal decay, and reduced thermal conductivity 18 . These issues came into effect from factors like poor bonding between polymer blends and protective layers, concerns regarding stabilization, and so on 19,20 . This may slow down the flow of heat between the PCM and its surroundings when it undergoes thermal cycling, which in turn can decrease the efficiency with which energy is stored and released 21 .…”

Phase change materials (PCMs) have drawn considerable attention in recent years due to their capability of storing and releasing thermal energy during phase transformation. However, traditional PCMs face challenges like limited thermal conductivity, leakage while phase transformation from solid to liquid, thermal degradation, and durability. Researchers have concentrated on creating shape‐stabilized PCMs (SSPCMs) employing polymers as the supporting matrix to overcome these difficulties and incorporating highly thermally conductive additives to improve thermal conductivity. Compared to conventional PCMs, polymer‐based SSPCMs are often more flexible, lightweight, and durable and may be easily customized according to specific applications. Various factors like PCM loading, thermal cyclability, cost‐effectiveness and environmental concerns must be considered while constructing polymer‐based SSPCMs. This review paper comprehensively explored various polymers, including polyurethane, polyacrylates, polyolefin, and so on, as promising supporting materials for SSPCMs due to their relatively high mechanical strength, compatibility with PCM, excellent thermal stability, and chemical resistance. Natural polymers like chitosan, cellulose, and starch are also considered for eco‐friendly solutions. We have also discussed about specific properties of each polymer, their cost‐effectiveness, and the environmental impact while developing such SSPCMs to guide researchers in material selection. Applications of polymer‐based SSPCMs in solar energy storage, medical devices, building materials, electronics, transportation industry, and waste heat recovery are briefly discussed. Finally, some future development areas have been discussed to attract the attention of new researchers in this field. The information provided in this review will assist readers in understanding polymer‐based SSPCM and selecting their desired polymer for support material with diverse application methods.

“…The key advantages of using PCMs include their wide range of melting temperatures, high latent heat storage (LHS) capacity, thermal stability, and eco-friendliness [4]. However, PCMs do have certain limitations, such as lower thermal conductivity (TC) and suboptimal light absorption properties, which hinder their practical application in solar thermal systems and lead to slower charging and discharging rates [5], [6]. As a solution, some researchers suggest incorporating highconductive nanoparticles into the PCM to improve its heat conductivity and modify other properties [7]- [9].…”

Thermal Energy Storage (TES) is a valuable tool for improving the energy efficiency of renewable energy conversion systems. One of the most effective methods for harnessing thermal energy from solar sources is through energy storage using phase change materials (PCMs). However, the thermal performance of PCMs is hindered by their low thermal conductivity. This research focuses on enhancing the thermal performance of salt hydrate PCM using multi-walled carbon nanotubes (MWCNTs) and surfactants. Through experimental investigations, a salt hydrate PCM with varying concentrations of MWCNTs (ranging from 0.1% to 0.9%) was prepared using a two-step technique and their thermophysical properties were thoroughly characterized. Various techniques such as field emission scanning electron microscope, thermal conductivity analyzer, ultraviolet-visible spectrum, thermogravimetric analyzer, and Fourier transform infrared spectroscopy were utilized to study the effect of surfactant on the nanocomposites and examine their morphology, thermal conductivity, optical properties, thermal stability, and chemical stability. The results indicated that the inclusion of MWCNTs with salt hydrate significantly improved the thermal conductivity by 68.09% at a concentration of 0.7 wt %, compared to pure salt hydrate. However, this enhancement in thermal performance was accompanied by a reduction in optical transmittance in the developed nanocomposite PCM. Additionally, the formulated nanocomposite demonstrated excellent thermal and chemical stability up to temperatures as high as 468 °C. As a result, this nanocomposite shows great promise as a potential candidate for solar TES applications, offering favourable characteristics for efficient energy storage from solar sources.
