This article investigates the effect of aluminum doping on the thermal conductivity and other thermoelectric properties of nanostructured Zn1•XAlXTe (0 ≤ X ≤ 0.15) for a temperature range of 300 K – 600 K. The thermal conductivity was measured using the transient plane source (TPS) technique by a thermal constants analyzer. It was found that with increasing doping of aluminum, the thermal conductivity decreased, and with increasing temperature thermal conductivity also decreased. The decreasing of thermal ...
Silicone materials have high electrical and thermal insulation properties that are useful for engineering applications. In this study, vapour grown carbon nanofibers (VGCNF) were produced by two different methods and were added to silicone rubber to improve conductivity. A thermal constant analyser measured the thermal conductivities of the silicone and its composites using the transient plane source (TPS) method. Results showed that thermal conductivities of the roll-mill produced VGCNF/silicone ...
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....
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 (...
