AbstractThe application of phase change materials (PCMs) for solar thermal-energy storage has received considerable attention in recent years due to their high storage density [1,2]. A series of microencapsulated PCMs (Micro-PCMs) with good phase change behavior have been synthesized through in-situ polymerization and the applications of the obtained Micro-PCMs in thermal regulatory of gypsum boards are presented in this study. Scanning electron microscope (SEM) images reveal that the Micro-PCMs were dispersed homogeneously in the gypsum boards (as seen in Fig.1). Differential scanning calorimeter (DSC) results show that all the gypsum boards with different weight percent of the Micro-PCMs possess good phase change behavior (see Fig.2). The melting and freezing temperatures as well as the latent heat of the gypsum board with 60 wt.% Micro-PCMs and 3 wt.% glass fibers are quite suitable for the potential thermal energy storage of building applications. Thermal cycling tests indicate that the gypsum board with Micro-PCMs maintains good thermal stability after 10 melting-freezing cycles. Furthermore, the gypsum boards with Micro-PCMs show a good thermal-regulated property as seen in Fig.3. As the around temperature is 50 oC or 0 oC, the temperature of the boards can be kept in the rage of 20-27 oC for about 20 min due to the phase change of the inside Micro-PCMs. The mechanical property of the gypsum board with Micro-PCMs is highly improved after adding 3 wt.% glass fibers. From the above results, it can be concluded that the gypsum boards with Micro-PCMs have a good potential for thermal energy storage purpose of building materials.; The application of phase change materials (PCMs) for solar thermal-energy storage has received considerable attention in recent years due to their high storage density [1,2].
