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....
A series of polymer-matrix composites were synthesized by using a variety of carbon nanotubes (single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs) and multi-walled carbon nanotubes (MWCNTs)) and a polymer matrix (either polystyrene (PS) or poly(methyl methacrylate) (PMMA)). Different surfactants and polymerization methods were also used in order to generate a wide range of different composites. These different composites were all tested for thermal and electrical conductivity and characterized ...
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....
A 3D carbon nanotube (CNT) network is explored and how potassium or iodine doping can affect the thermoelectric properties of this network. Through in-situ nanoscaling, this CNT network was combined with polyaniline (PANI) and increased the thermoelectric performance of PANI while maintaining the flexible structure of the 3D CNT network. This composite has one of the lowest thermal conductivities of any reported CNT materials....
