| 제목 | Preparation of Graphene/Paraffin Composite Phase Change Materials by Silica Aerogel |
| 초록 | Graphene/paraffin composite PCM are high thermal conductivity. However, graphene/paraffin composite PCM are form-instability when the temperature reached to melting the temperature of paraffin. Porous materials are good for shape stable of liquid-solid PCM. Among the porous materials, silica was excellent specific surface area, large pore volume, high adsorption capacity, and chemical inactive. In this study, silica aerogel was used to prepare the form stable graphene/paraffin composite PCM. The morphologies of the PCM were examined by the SEM. The Surface properties of the PCM were also investigated by FT-IR and XPS. The average pore diameters of the PCM were assessed by BET surface area analyzer. Thermal properties were observed by DSC and TGA. Thermal conductivity of the PCM was analyzed to compare difference before and after cycling test |
