Carbon nanotubes (CNTs) have extremely high thermal conductivity and can raise the thermal conductivity of a polymer matrix when used as an additive. Previous research has shown that random CNT orientation in polymer matrices gives a much lower thermal conductivity value than a specific alignment direction. This project tested the thermal conductivity of oils and polymers. Results were encouraging, with the thermal conductivity of the composites increasing linearly with the ...
This study is investigating how the thermal conductivity of a PMMA polymer filled with multi walled carbon nano tubes (MWNT) changes with temperature, and wt % MWNT. Also, the series, parallel, Lewis/Neilson and empirical formula models were used to quantify how well the measured values correlate with the calculated values. The thermal conductivity was measured with a transient plane source (TPS) method. The thermal conductivity of the polymer increased with ...
The purpose of this study was to develop adhesive epoxy resins that used multiwalled carbon nanotubes (MWCNTs) to enhance thermal conductivity and dispersion in the polymer matrix. An analyzer measured the thermal conductivity of the MWCNTs-based epoxy adhesives using the transient plane source (TPS) method. Results showed that the addition of MWCNTs improved the coefficient of thermal conductivity of the epoxy resin in comparison to pristine epoxy and epoxy (EP)...
As nanotechnology becomes increasingly important, researchers are investigating methods to decrease the size of electronics. Carbon nanotubes (CNTs) have potential applications in nanoelectronics because of their high thermal conductivity and miniscule size. This study had many focuses, but a TPS used the transient plane source method to specifically measure the thermal conductivities of CNT-fabricated thermal pastes. Results showed that the thermal conductivities varied depending on filler content, but were comparable ...
Conductive polymer composites (CPCs) contain high concentrations of carbon nanotubes (CNTs) to maximize electrical conductivity. However, high nanoparticle concentrations degrade other important properties of CPCs. This study produced CPCs using ultrahigh molecular weight polyethylene (UHMWPE) fillers in place of CNTs in an attempt to maintain important physical and mechanical properties. A thermal analyzer measured the thermal conductivity of the CPC samples using the transient plane source (TPS) method. Results showed ...
