Abstract: A composite PCM was prepared from n-octadecane and mesoporous silica (MPSiO2) nanoparticles. The nanoparticles were added in quantities ranging from 1 wt. % to 5 wt. %, and the thermal conductivity of each composite sample was determined as a function of temperature. The most significant enhancement in thermal conductivity was observed in the sample containing 3 wt. % MPSiO2 nanoparticles. The viscosity of the composite samples was also investigated and it was found that at mass fractions greater than 3%, the viscosity illustrated non-Newtonian behavior.
