Phase Change Materials (PCMs)

Phase Change Materials (PCMs) are substances that absorb and release thermal energy as they change between solid and liquid states. When they heat up, they melt and store heat; when they cool, they solidify and release stored heat. This property allows PCMs to regulate temperature by maintaining near-constant heat levels during the phase transition. They are used in applications like building insulation, temperature-sensitive packaging, and thermal energy storage systems to improve energy efficiency and maintain desired temperature conditions effectively.
