Thermal Conductivity Measurements in Phase Change Polymer Composites Doped with Carbon Nanotubes
Energy savings can efficiently be carried out in storing thermal energy when it cannot be used otherwise. Usage of Phase Change Materials (PCMs) is an effective mode to store energy within a small volume. However, most of PCMs have low thermal conductivity which leads to low charging/discharging heat rates. To increase this conductivity we have created composites made of a mixture of paraffin and polymer on one hand and, paraffin/polymer with carbon nanotubes on another hand. The effective thermal conductivity of these composites has been measured and some results are presented in this communication. Comparison was made with a classical model.
