Vapor-grown carbon nanofiber (VGCF) was functionalized by the covalent bonding of polylactide (PLA) in order to generate a composite known as PLA-g-VGCF. This is a multiple step process and does not produce the same composites as regular melt compounding (VGCF/PLA). This new composite was characterized by x-ray photoelectron spectroscopy, TGA and TEM in order to quantify and qualify the newly prepared composites, which showed 'remarkable improvement' over the melt ...
Ni-coated single-walled carbon nanotubes (SWNTs) were dispersed in four fluids (of varying viscosities) to create four different nanofluids. Due to the magnetic properties of the coated nanotubes the researchers induced a magnetic field to increase the thermal conductivity of the nanofluids. The increase in thermal conductivity was due to the alignment of the carbon nanotubes into chains due to the magnetic field. A Thermal Constants Analyzer was used to measure ...
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 compacted Bi0.5Sb1.5Te3 nanoplatelets are synthesized using hydrothermal methods, followed by cold pressing and sintering at temperatures between 300°C and 380°C. A variety of thermal, mechanical and electrical analyses are then performed on the synthesized nanoplatelets including: TPS technique for thermal conductivity, SEM/TEM/AFM to elucidate the mechanical and physical properties of the nanoplatelets, and the Oxford closed cycle cooler cryostat for measurement of electrical ...
The addition of graphene nanoplatelets (GNP) to a paraffin-based solvent, eicosane was performed at various wt.% and subsequently the synthesized GNP/eicosane composites were analyzed by a variety of machines. The characterization of the GNP/eicosane composites was performed by the TPS technique for the measurement of thermal conductivity from 10°C to 35°C. At a wt.% of 10 GNP filler the composite had a thermal conductivity four times that of unfilled ...
