Resumen: The present work studies a Phase Change Slurry (PCS) as a proposed Thermal Energy Storage (TES) medium. Microencapsulation is an advanced technology to implement PCMs (Phase Change Material) avoiding leakage from building materials. The morphology and physicochemical properties of this Microencapsulated Phase Change Material (MPCM) sample were analyzed using some analytical techniques like Scanning Electron Microscopy (SEM), Infrared Spectroscopy (FT-IR), Thermogravimetrical Analysis (TGA), Differential Scanning Calorimeter (DSC), and Atomic Force Microscopy (AFM). The results showed that Micronal® DS 5007 is a suitable candidate to be used as slurry in active systems due to their studied mechanical properties.
