Phase change materials
상변화 물질은 고체-액체 전이를 통해 혁신적인 열에너지 저장 솔루션을 제공하며, 현재 진행 중인 연구를 통해 주요 엔지니어링 과제들이 해결되고 있습니다.

Phase Change Materials (PCM) store and release thermal energy through solid-liquid transitions at near-constant temperature, exploiting latent heat capacities orders of magnitude greater than sensible heat storage. Research spans material classes — paraffins, salt hydrates, fatty acids, eutectic mixtures — alongside critical challenges in thermal conductivity enhancement, supercooling mitigation, long-term cycling stability, and containment through micro- or macroencapsulation.
