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....
High speed microscopy was used to allow real time visualization of the movement of nanoparticles made up of single-walled carbon nanotubes (SWCNT) and Fe2O3. An electrostatic force was induced to the nanotube/Fe2O3 composite and caused perfect conjugate structures which result in excellent thermal, electrical, and mechanical properties. The alignment of the carbon nanotubes in nanosuspensions may offer new opportunities for the development of nanofluids....
Thermally Exfoliated Graphite Oxide (TEGO) was mixed with natural rubber (NR) using a two-roll mill but the mixing of the TEGO with the NR didn't proceed as expected. Therefore the researchers had to modify the procedure and decided to pre-mix the TEGO and NR in an ultrasonically-assisted latex co-coagulation process followed by two-roll milling resulted in significant improvement in the thermal and electrical properties of the nanocomposite compared to the ...
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 ...
The authors observed a remarkable synergistic effect when they used multi-graphene platelets (MGPs) and multi-walled carbon nanotubes (MWCNTs) together in an epoxy composite. The use of these two fillers together increased the tensile strength, thermal conductivity, solubility and compatibility relative to the various individual components. The 1D nanotubes inhibit the aggregation/stacking of the platelets and thus result in high contact area between MGP/MWCNT and the polymer matrix....
