Methods for the Synthesis of Phase Change Material Microcapsules with Enhanced Thermophysical Properties—A State-of-the-Art Review

Thermal energy storage (TES) has been identified by many researchers as one of the cost-effective solutions for not only storing excess or/wasted energy, but also improving systems’ reliability and thermal efficiency. Among TES, phase change materials (PCMs) are gaining more attention due to their ability store a reasonably large quantity heat within small temperature differences. Encapsulation is cornerstone in expanding applicability PCMs. Microencapsulation proven, viable method containment retention PCMs tiny shells. Currently, there numerous methods available synthesis mPCMs, each which its own advantages limitations. This review aims discuss, up date, different manufacturing approaches preparing PCM microcapsules (mPCMs). The highlights potential used enhancement thermophysical properties, including transfer enhancement, supercooling suppression, shell mechanical strength. article will help end users better understand current microencapsulation technologies provide critical guidance selecting proper based on required final product specifications.
