In this work, a new microencapsulated phase change material, paraffin@ silica (SiO2)/graphene oxide (GO), is prepared by two steps: engulfing paraffin with silica by in situ hydrolysis and poly condensation of tetraethoxysilane and the modification of the SiO2 shell with GO. The paraffin@SiO2/GO composite is composed of spherical capsules with diameters of ~20um. Raman spectrometer analysis verifies...
