Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
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 fatty acid stearic acid has been widely studied for its use in thermal energy storage applications as a phase change material (PCM). Stearic acid shows promise for this application because of its high volumetric storage density and its favorable thermal properties; however, two properties of stearic acid limit its use as a PCM: its low thermal conductivity and its propensity to leak liquid during the phase change process. This ...
