Abstract
Abstract Energy storage nowadays is a cumbersome process that needs to be exploited for its best use. This review paper discusses the challenges of efficiently utilizing energy storage and proposes phase-change materials (PCMs) with Nano-particle reinforcement as a solution, particularly for storing solar thermal energy. Various synthesis methods for PCM, including impregnation and encapsulation, are examined, emphasizing factors like particle size, shape, and solid content. Carbon-based materials, including carbon nanotubes and graphene oxide, emerge as superior options due to their reliability, cost-effectiveness, lightweight nature, and high heat transfer efficiency, with minimal environmental impact. This review highlights the enhanced thermal conductivity of Nano-particle-reinforced PCM composites, emphasizing their thermally stable, durable, and conductive properties. Additionally, it discusses thermal performance through techniques like DSC, TGA, and DTG, along with material characterization methods such as FTIR, SEM, XRD, EDX, and XPS analysis. Overall, the research underscores the promising potential of Nano-particle-reinforced PCM composites for efficient energy storage and thermal management applications.
