Section snippets Approaches for obtaining SS-PCMs. There are currently two main approaches taken to obtain SS-PCMs. In the first approach, the arrangement of relatively small molecules changes from one crystalline phase to another when absorbing or releasing heat [27].These SS-PCMs materials are also referred to as "plastic crystal" solid …
Phase change materials (PCMs) experience transitions in response to alterations in the surrounding temperature, effectively either absorbing heat from, or releasing stored thermal energy into, the environment [1,2].During latent heat storage, PCMs exhibit near-isothermal characteristics with high energy density.
