This study looked at the use of two different fillers to improve the thermal properties of an epoxy resin. The two fillers were multi-walled carbon nanotubes (MWCNTs) and aluminum nitride (AlN). Through the use of poly(glycidyl methacrylate) (PGMA) and a zirconate coupling agent the MWCNTs and AlN particles respectively were added to the epoxy resin. Through the use of 1 vol.% MWCNT and 25 vol.% AlN the researchers were able to ...
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, ...
