We report here on the potential of organic phase-change material gel-in-water (OPCMG/W) emulsions as thermal-energy storage and heat transfer fluids. Gelation of OPCM droplets in OPCM/W emulsions enhanced the colloidal stability against temperature change in the range of -1 to 40℃ and prevented the supercooling of OPCM droplets in the emulsions. Furthermore, the thermal properties of OPCMG particles in OPCMG/W emulsions were similar to those of OPCM alone.
