Improving interfacial bonding and load-transfer in nanocomposite through grafting diethyltoluenediamines on SWNTs Conference Paper uri icon


  • In this study, diethyltoluenediamines (DETDA) was grafted to single-walled carbon nanotubes (SWNTs) through one-step diazotization for improving interfacial bonding and load-transfer in SWNT/epoxy nanocomposites. Characterization results of Fourier Transform Infrared Spectroscopy validated covalent bonding between DETDA and carbon nanotubes. The degree of SWNT functionalization was about 2% based on thermo-gravimetric analysis. Interfacial bond strength was estimated in the presence of chemical bonding and the calculation results indicated that the interfacial shear strength in the presence of functionalized carbon nanotubes was enhanced by a factor of 3.56. The storage modulus of functionalized SWNTs/epoxy nanocomposite was dramatically improved after functionalization and almost reached the theoretical prediction value. Results suggested an improved load-transfer was achieved in the functionalized SWNT reinforced epoxy composites.
