Preparation of plasma reduced graphene oxide / organic phase change material composites for latent heat storage application |
| 초록 |
Various organic phase change materials (PCMs) – paraffin, polyethylene glycol (PEG) and octanoic acid – were absorbed into the expanded structure of plasma-reduced graphene oxide (PrGO) to fabricate diverse PrGO/PCM composites. Because of large surface area and expanded structure, organic PCMs could be successfully impregnated into the PrGO structure. As-prepared PrGO/PCM composites had highest thermal conductivity value of about 0.75 W/m K which was about 3-fold increase of that of the pristine PCMs. Furthermore, thermal stability was also increased while there was no decrease in heat of fusion because of low fraction of PrGO composition (1 wt%). These simply fabricated PrGO/PCM composites can be applied to thermal energy management and solar energy storage. |
