Raw multi-walled carbon nanotubes (r-MWCNTs) and Cu nanoparticles are dispersed in an epoxy matrix in varying quantities to create composite polymers with enhanced thermal conductivities. A study was then conducted to determine if the boundary thermal contact resistance could be reduced by increasing the thermal conductivity. The boundary thermal contact resistance was found to be approximately constant across all samples containing the copper nanoparticles. The boundary thermal contact resistance was ...
Composite phase change materials were prepared using stearic acid, coffee grounds, and graphite. The coffee grounds were used as a supporting material for the stearic acid, and the graphite was added in an effort to enhance the thermal conductivity of the composite. The composites were characterized by SEM and FT-IR, the thermal conductivity was determined by the phase change temperature and latent heat were determined by differential scanning calorimetry. The ...
The laser floating zone method was used to prepare Pb doped Bi2-xPbxBa2Co2Oy thermoelectric materials with x=0, 0.2, 0.4, and 0.6. The highest power factor reported was obtained at 650oC for the 0.2 Pb doped samples. This value was higher than that for pure laser grown Bi2Ba2Co2Oy materials. The thermal conductivity was decreased, as is desired in thermoelectric materials....
The authors prepared silica aerogel/polyurethane composites by two different methods for the comparison of the two methods. The objective was to study the thermal insulation and hydrophobic properties of the composites to evaluate their potential for use as fabric membranes. It was found that the composites are better thermal insulators than polyurethane alone, and that they also have improved hydrophobic properties. It was also determined that the thermal conductivities ...
