Li2TiO3 single crystals were grown using the flux method. These crystals were then characterized by the TPS method for thermal conductivity and a variety of other methods in order to determine the density and composition of the crystals....
The authors obtained a collection of crosslinked closed cell polyethlyene foams from a commercial supplier and then characterized the thermal properties of these foams. The characterization involved the use of the TPS technique to measure thermal conductivity, thermal diffusivity and specific heat capacity. It was found that increasing density resulted in a decreased thermal diffusivity and an increased specific heat capacity per unit volume. A theoretical model was developed to ...
The low thermal conductivity of paraffin hinders its ability to be used as a PCM, and so in this article the authors created a composite made up of paraffin and micron-size graphite flakes (MSGFs) in order to hopefully increase thermal conductivity and energy storage capabilities. The results showed that increasing concentrations of MSGFs corresponded to 'enormous' increases in thermal conductivity. The addition of MSGFs to paraffin did not affect its ...
Single and multi walled carbon nanotubes were prepared using the floating catalyst chemical vapor deposition method and were subsequently added to polymethylmethacrylate (PMMA) to generate a composite material. The thermal properties of these composite materials were studied. The effect of acid treatment on these composite materials was also studied and was found to decrease the thermal conductivity of the materials. The addition of CNTs to the PMMA resulted in an ...
Two different sets of phase change materials were made by adding either graphene or exfoliated graphite nanoplatelets (xGnP) to paraffin in hot toluene. The thermal and stability properties of these newly synthesized composites were then studied using the TPS method. The addition of xGnP led to a higher thermal conductivity while the addition of graphene led to a higher electrical conductivity. Graphene was found to be better at stabilizing the ...
