Multi walled carbon nanotubes (MWCNTs) and carbonized resorcinol-formaldehyde (RF) resin were used to create a conducting aerogel with a high electrical conductivity and Seebeck coefficient but a low thermal conductivity. The addition of the MWCNTs caused the figure of merit (ZT) for the aerogel to increase by two orders of magnitude. The researchers determined that it was possibly to control the electrical conductivity, thermal conductivity, and Seebeck coefficient independently of ...
In this paper, a thermally conductive insulated inorganic nanolayer of AlO(OH) was coated onto the surface of multi-walled carbon nanotubes (MWCNTs) to create a novel thermally conductive material. The coating of MWCNTs with this inorganic layer can effectively avoid the formation of electrically conductive networks in the Pi matrix and provides excellent thermal (conductivity) properties....
Nanocomposites were prepared by the mixing of multi-walled carbon nanotubes (MWCNTs) with nitrile and hydrogenated nitrile elastomers (NBR and HNBR). A variety of methods including TEM, SEM, and XRD were used in order to investigate the morphology of the nanocomposites. Many mechanical properties of the nanocomposites were measured and reported. A machine was used to measure the thermal properties of the synthesized nanocomposites....
This study looked at the use of two different fillers to improve the thermal properties of an epoxy resin. The two fillers were multi-walled carbon nanotubes (MWCNTs) and aluminum nitride (AlN). Through the use of poly(glycidyl methacrylate) (PGMA) and a zirconate coupling agent the MWCNTs and AlN particles respectively were added to the epoxy resin. Through the use of 1 vol.% MWCNT and 25 vol.% AlN the researchers were able to ...
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....
