Özet
This study provides a comprehensive literature-based analysis of the long-term thermal and mechanical performance of dynamic phase change materials (DFMs), which play a critical role in sustainable energy storage systems. Unlike short-term studies that dominate the field, this work synthesizes and compares reported findings from previous experimental research, focusing on thermal cycling behavior, microstructural changes, and mechanical strength degradation. The review highlights that DFMs commonly experience thermal efficiency losses of 5–15 % and mechanical strength reductions of up to 40 % over extended cycling, primarily due to crack formation, void generation, and structural fatigue. Encapsulation techniques and nanoadditives such as SiO2, TiO2, and carbon nanotubes have been shown to mitigate degradation by enhancing thermal conductivity, reducing leakage, and delaying crack propagation. Hybrid approaches, including the integration of encapsulation with nanoadditives or metal foams, demonstrate further potential in extending material durability. Environmental and economic perspectives are also considered, emphasizing the importance of balancing performance improvements with sustainability and cost-effectiveness. The study concludes by identifying key limitations of current research and outlining future directions, including environmental durability tests, techno-economic assessments, and AI-driven optimization for material design. This synthesis provides a stronger foundation for improving the long-term stability of DFMs and supports their integration into next-generation sustainable energy storage applications.
