In this study, a new method was proposed for the preparation of a stable Al2O3-paraffin nanocomposite phase change material (NCPCM). Sodium stearoyl lactylate (SSL) was used as the surfactant to improve the dispersion of Al2O3 nanoparticles (2.5, 5, 7.5, and 10 wt.%) in paraffin with a SSL/Al2O3 mass ratio of 1:3.5. After preparation, one group of the samples was placed in an incubator at a temperature...
A new kind of nano composite phase change material (NCPCM) was prepared using sodium stearoyl lactylate (SSL) as a surfactant to improve the dispersion of the Al2O3 nano-particles (with 2.5, 5, 7.5, and 10 wt.%) in paraffin with a SSL/Al2O3 mass ratio of 1:3.5. To evaluate the efficiency of the prepared PCMs, the melting rate of them at a temperature range of 50–60 °C and the effective thermal conductivity...
