PANI/tetradecanol/MWNTs composites were prepared via in-situ polymerization and analyzed for their use as phase change materials. The MWNTs were randomly dispersed in the composite and it was determined that the PCM was form-stable and that phase separation of the MWNTs and PANI/tetradecanol wouldn't occur....
A series of melamine-formaldehyde microcapsules were synthesized using an in-situ polymerization and subsequently characterized for their thermal and structural properties. SEM and FT-IR were used to investigate the structural properties and DSC and TGA were used to investigate the thermal properties. The authors concluded that the thermo-physical properties of the microcapsules were related to the synthesis conditions and the core content of the capsules....
Expanded graphite (EG)/paraffin composite materials were prepared with the weight % of EG varying from 0 to 10%. It was found that the addition of EG to paraffin greatly improved the thermal conductivity of the material. The melting and freezing points of the PCM were compared to those of the pure paraffin. Also the heat storage/retrieval rates were studied and demonstrated improved properties....
The researchers proposed a method used to measure the thermal conductivity and heat capacity of low thermal conductivity materials with accuracy better than 10%. DSC was also used to determine thermal contact between the sample and the DSC furnace....
Nano-graphite (NG)/paraffin composites were prepared as composite phase change materials. The addition of NG increased the thermal conductivity of the composite material. The material containing 10% NG had a thermal conductivity of 0.9362 W/mK...
