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 ...
The authors observed a remarkable synergistic effect when they used multi-graphene platelets (MGPs) and multi-walled carbon nanotubes (MWCNTs) together in an epoxy composite. The use of these two fillers together increased the tensile strength, thermal conductivity, solubility and compatibility relative to the various individual components. The 1D nanotubes inhibit the aggregation/stacking of the platelets and thus result in high contact area between MGP/MWCNT and the polymer matrix....
As technology advances, the need for inexpensive polymer-based composites possessing high thermal conductive properties has become more and more important. Previously, the addition of thermal conductive particles, such as alumina, boron nitride and alumina nitride, has caused an increase in the thermal conductivity of the composite. Although an increase in thermal conductivity is present, an increase in fabrication costs is also experienced as a higher quantity of particles is required, ...
