However, the tendency of organic phase change materials to leak out during the phase transition process, limits their practical applications in thermal energy storage. The shape-stabilization is an effective strategy to prevent the leakage and enhance the energy storage capacity of organic phase change materials.

Latent thermal energy storage using phase change materials (PCMs) could provide a solution to that problem. PCMs can store large amounts of energy in small volumes, however, the main issue is the low conductivity of PCMs, which limits the rate that energy can be stored due to the slow melting and solidification processes.
