Abstract

In this study, a range of reversible thermochromic microencapsulated phase change materials (RTPCMs) encapsulated in silica (SiO2) microcapsules modified with a silane coupling agent was successfully created and produced. The structure and composition of these thermochromic microcapsules were analyzed using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM), while their heat storage capacity was evaluated using differential scanning calorimetry (DSC). SEM images revealed that these microcapsules exhibited a spherical shape with a well-defined core–shell structure. Both DSC and thermogravimetric (TG) analyses demonstrated that microcapsules modified with MPTMS exhibited a…
