“…11,12 The high conductive fillers such as metal and metal oxide nanoparticles have been used as additives by various researchers in different PCMs such as Cu, 13 Al 2 O 3, 14 Ag, 15,16 ZnO, 17 and VO 2. 12 Similarly, the carbon-based nano-fillers 11,13 have been used to increase the conductivity of the PCMs including that of graphene, 23,24 graphene oxide (GO), 25,26 reduced GO, 27 carbon fibers, 28,29 carbon nanotubes, 30,31 graphite, expanded graphite, [32][33][34][35][36][37] biomass derived carbon, 38,39 etc. Ma et al 40 developed the PCMs based on paraffin, expanded graphite and nano-metal particles for the personal home cooling system.…”
