Impact transition temperature
WitrynaUpon heating and cooling, polymers experience distinct phase transitions when passing through specific temperatures. When temperature is raised, they physically transition from solid-like glassy to rubbery, and in the case of thermoplastics from rubbery to liquid like flow with additional heating. Witryna10 kwi 2024 · Hydrated salt phase change materials (PCMs) can play an important role in the temperature regulation of buildings by storing and releasing latent heat. However, hydrated salt PCMs are affected by phase separation, supercooling, and leakage, which greatly limit their application. In this study, an innovative modified calcium chloride …
