Multiwalled carbon nanotubes (MWCNT) have applications in the aeronautic industry. This study examined how the concentration of MWCNT affects the electrical and thermal conductivities of nanocomposites. A thermal analyzer (TPS) measured the thermal properties of the nanocomposites using the transient plane source (TPS) technique. Results showed that thermal conductivity of the samples increased with MWCNT concentration and temperature, but the phenoxy-MWCNT nanocomposites had higher thermal properties than the PES-MWCNT nanocomposites....
Adding metallic nanoparticles to a conventional fluid increases the thermal conductivity of the solution. In this study, flaked boron nitride (BN) and high-aspect-ratio multi-walled carbon nanotubes (MWCNTs) were added to epoxy composites to increase thermal conductivity. A thermal analyser measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that adding a small volume of MWCNT to the epoxy composite significantly improved thermal conductivity ...
The authors have developed a method for the functionalization of single-walled carbon nanotubes (SWCNTs). The functionalization of the SWCNTs is useful in helping to produce a better dispersion of nanotubes throughout a polymer matrix. Better dispersion of nanotubes was thought to result in an improvement in the mechanical, electrical, and thermal properties of nanocomposite polymers. It was determined that the method produced effective surface modification of the nanotubes. The elastic ...
Carbon nanotubes (CNTs) combined with inorganic matrices are not structurally sound unlike singular CNTs which have good mechanical performances. Borosilicate glass, commercially known as Pyrex, is durable but has yet to be successfully fabricated using the sol-gel technique. In this paper, the sol-gel technique was used to manufacture borosilicate glass matrix composites with multi-walled carbon nanotubes (MWCNTs). The technique measured thermal conductivity of the materials using the transient plane source (...
A nanoparticle-enhanced phase change material (NePCM) is prepared by the dispersal of carbon nanotubes in 1-dodecanol. The objective of this experiment was to determine if the addition of nanoparticles could increase the thermal conductivity of the base PCM while resulting in a NePCM that would still have the required properties of a functional PCM. It was found that the thermal conductivity was enhanced through the addition of the carbon nanotubes; ...
