Quick and Scalable Microwave Method for Making Efficient Heat Storage Materials

What is it about?

The study explored a novel microwave-assisted (MWA) synthesis method for creating bis(dodecylammonium) tetrachloromanganate, a solid-solid phase change material (PCM), as a rapid and scalable alternative to the traditional solvothermal (ST) process. This approach significantly reduced reaction time by 75% and improved phase transition enthalpy by 7.9% compared to ST synthesis. The research also noted a delay in thermal breakdown by 20 °C, suggesting enhanced thermal performance. Characterization techniques such as XRD, FTIR, DSC, and TGA confirmed increased crystallinity and thermal stability. The material was directly compacted into pellets using pressure sintering without binders, indicating potential for practical use in thermal storage modules. These findings provide a sustainable route for producing high-performance solid-solid PCMs for thermal energy storage applications.
