Inorganic salt hydrates are the most attracting phase change materials (PCMs) due to their high latent heat and low cost availability. The microencapsulation of these salt hydrates result in the improvement of heat transfer rates, thermal stability, and compatibility with various materials. However, their capsulation techniques are seldom known in comparison with organic PCMs. We have tried to microencapsulate sodium acetate trihydrate as a PCM with hybrid polymers by inverse interfacial polymerization. Several organoalkoxysilanes were used to provide a hybrid properties in order to mediate hydrophilic core and hydrophobic shell. The type and HLB values of surfactants, pH of reaction medium, and the ratio of ingredient were analyzed in the view of encapsulation possibility and performance of core PCM, which include the size and morphology of core-shell particles and essential thermal properties as a PCM. |
