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 ...
Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs enhanced the thermal conductivity of the electrodes by ...
The purpose of this this study was to graft polymer chains onto the surface of carbon nanotubes (CNTs) to examine the morphology and thermal properties of the epoxy composites in comparison to multiwalled carbon nanotubes (MWCNTs). A thermal analyzer measured the thermal conductivity of the nanocomposites using the transient plane source (TPS) technique. Results showed that the addition of Glycidyl methacrylate (GMA) to the MWCNTs/epoxy composites significantly enhanced thermal ...
As electronic devices approach nanometer scales, heat distribution becomes nonuniform and hot spots begin to form. Integrating graphene into nanoelectronics enhances thermal conductivity and heat flow which mitigates hot spots. In this experiment, large quantities of graphene were produced and thermal conductivity was measured by the transient plane source (TPS) method using an instrument. Results showed that the addition of graphene greatly improved the thermal conductivity of the thermal interface ...
