The procedure adopted is as follows. At first, 100 g of supporting material (EG or GNPs) and 300 g paraffin were mixed together and put into a vacuum chamber for about 2 h to evacuate the air from the composite PCM. Thereafter, the vacuumed composite PCM was kept on the filter paper to remove the redundant paraffin.
