Surface‐Engineered Cenospheres Encapsulating Phase Change Materials for Functional Cementitious Composites

open access: yesAdvanced Science, EarlyView.
The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using
