Abstract
Multi-walled carbon nanotubes (MWCNTs) and graphite nanosheets (GNS) reinforced epoxy nanocomposites are synthesized by solution mixing process. Various surface active groups on filler materials are analyzed and their effect on dispersion, interfacial bonding was correlated to the thermal conductivity and dimensional stability of the nanocomposites. Thermal conductivity of MWCNTs/epoxy nanocomposites was enhanced by 34% when compared to GNS/epoxy nanocomposites at room temperature. Improved dimensional stability was also observed in the case of MWCNTs/epoxy nanocomposites. Poor thermal properties of GNS/epoxy nanocomposites are due to formation of GNS agglomerates in the nanocomposites. © 2013 AIP Publishing LLC.
