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 ...
The thermal and rheological properties of n-octadecane, a phase change material, with dispersed TiO2 nanoparticles were investigated at varying temperatures. The properties were investigated in both the solid and liquid phases, with varying mass fractions of TiO2 nanoparticles. The thermal conductivity was found to be enhanced in all of the composite samples when compared to the thermal conductivity of pure n-octadecane, and the maximum enhancement occurred at 3 wt. % TiO2 in ...
