Abstract: In this paper, the authors discuss the preparation of microencapsulated phase change materials (PCMs). The PCMs used in this study were n-hexadecane and n-octadecane, and the shell was made up of poly(urea-formaldehyde). The effect of dispersing silver nanoparticles in the shells on the thermal storage properties of these encapsulated PCMs was also investigated. The enthalpies of fusion of the samples were determined experimentally, as was the thermal conductivity. It was determined that the encapsulated PCMs that were prepared had similar enthalpies to commercially available products, and the thermal conductivities of the samples were improved by the addition of silver nanoparticles. The authors concluded that these materials show promise for use in a wide range of industrial applications.
