Figure 1. (A-i) Graphical representation of principles of phase change of phase change materials (PCM), and (A-ii) schematic representation of phase change process in solid-liquid PCMs. (B) Classification of liquid crystals (LC). Typical phases of thermotropic LCs with the increase in temperature from crystal phase to liquid (isotropic, I) phase.
