Abstract
This paper presents thermophysical properties and dispersibility of some phase change nano-emulsions. The testing emulsions consist of surfactant aqueous solutions and n-hexadecane droplets as the phase change material, which are chemically dispersed in the solutions by means of D-phase emulsification method. Some samples of the emulsions are forced to undergo 10 cycles of melting and solidification process, and their dispersibility, DSC curve, droplet size distribution and viscosity are compared to those of the samples which are statically kept under room temperature. The results reveal that the testing emulsions have pretty stable properties even after they are molten and solidified repeatedly.
