Abstract: A nanoparticle-enhanced phase change material (NePCM) is prepared by the dispersal of carbon nanotubes in 1-dodecanol. The objective of this experiment was to determine if the addition of nanoparticles could increase the thermal conductivity of the base PCM while resulting in a NePCM that would still have the required properties of a functional PCM. It was found that the thermal conductivity was enhanced through the addition of the carbon nanotubes; however, the addition of the nanotubes was found to increase the viscosity drastically to the point that it is not sufficiently offset by the increase in thermal conductivity.
