Pristine and modified exfoliated graphite nanoplatelets (xGnPs and M-xGnPs, respectively) were dispersed into a paraffin wax phase change material (PCM) in an effort to raise the thermal conductivity of the PCM. The addition of pure xGnPs would decrease the electrical resistivity of the composite PCM, and thus its potential for use in electrical devices would be limited due to safety concerns. To eliminate this issue, the M-xGnPs were prepared. Samples ...
Two different sets of phase change materials were made by adding either graphene or exfoliated graphite nanoplatelets (xGnP) to paraffin in hot toluene. The thermal and stability properties of these newly synthesized composites were then studied using the TPS method. The addition of xGnP led to a higher thermal conductivity while the addition of graphene led to a higher electrical conductivity. Graphene was found to be better at stabilizing the ...
