Materials that can store latent heat (energy released or absorbed by a material or a thermodynamic system at constant-temperature process) during the phase transition are called phase change materials (PCMs). PCMs latent heat transition can be achieved with solid-solid, solid-liquid, solid-gas, and liquid-gas phase change. However, only solid-liquid phase change is used in advanced PCMs at commercial level, since other methods required large volume and high pressure.
Based on the technology of the material used, advanced PCMs are broadly categorized as inorganic PCMs, organic PCMs, bio-based PCMs and other PCMs. Organic PCMs are further classified as paraffin and non-paraffin materials; these materials melt and freeze repetitively without phase isolation and resulting degradation of their latent heat of fusion. Inorganic phase changed materials are further classified in salt hydrate and metallic. These advanced PCMs do not withdraw heat significantly and their heats of fusion do not decay with cycling. Bio-based advanced PCMs are mostly derived from plant oil or animal fat and poses higher biodegradability over others.
On the basis of their application in various fields the advanced PCMs can be categories as building and construction, energy storage, heating, ventilation and air conditioning (HVAC), shipping and transportation, and others including textiles and protective clothing.
