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 ...
