Abstract Mesoporous silica nanoscale microsphere (MSNM), with a special morphology, high porosity, large pore volume and specific surface area, was successfully prepared and used as the matrix material of lauric acid (LA) to prepare a favorable shape-stabilized phase change material (LA/MSNM). The porous network structure of MSNM is effective to prevent the leakage and enhance the thermal stability of LA/MSNM. For comparison, shape-stabilized phase change material of LA/AC, which contained commercially purchased active carbon (AC) and LA, was prepared by the same method. Characterizations of LA/MSNM and LA/AC, such as chemical properties, structure, thermal properties and crystallization properties were studied. The mechanisms of interaction between LA molecules and MSNM or AC were explicated. The results of TGA test showed that the LA/MSNM and LA/AC had superior thermal stability, and however, the melting and solidification enthalpies of LA/MSNM were much higher than that of LA/AC, which was attributed that the loading capacity of MSNM was better than that of LA/AC. All of the study results demonstrated that the mesoporous silica nanoscale microspheres of MSNM synthesized in this study possessed the potential for practical applications as a suitable supporter of organic phase change materials.

Positive Effect

The building energy conservation has an important role in the energy field. Lightweight materials have been extensively used. By compositing the capric acid (CA) and lauric acid (LA) eutectic and using the expanded perlite (EP) as the matrix, a phase change material (PCM) was prepared and studied in laboratory. The mass fraction of this PCM reached at 60% through direct immersion for 24 hours. Differential scanning calorimeter (DSC) testing results indicated that the melting temperature of the PCM is 18.0°C, and the latent heat is 73.77J/g. From 1000 times cycling and heat-release characteristic test, this PCM was found to be stable well. After 2(wt)% graphite added in, solidification time of the PCM decreased by some 30%, the thermal conductivity improved. Application showed that the PCM has a positive effect on improving indoor environmental temperature.
