A sort of new phase change material (PCM) microcapsules based on n-octadecane core and calcium carbonate (CaCO3) shell was synthesized through a self-assembly method to enhance the thermal conductivity and serving durability. Fourier transform infrared spectra confirmed that the CaCO3 wall...

A new silica encapsulation technique toward n-octadecane PCM (phase change material) was developed through sol–gel synthesis using sodium silicate as a silica precursor. Fourier transform infrared spectra confirm the chemical composition of the synthesized microcapsules, and wide-angle X-ray...
