Description
Summary:A critical challenge for initiating many applications of the carbon nanotubes （CNTs） is their dispersion inorganic solvent or in polymer melt. In the present study, we described a novel strategy for fabricating carbon nanotubes（CNTs）-reinforced epoxy nanocomposite by utilizing aniline trimer （AT） as the noncovalent dispersant. Tensile testingshowed that the tensile modulus of the CNTs-reinforced epoxy composites was considerably improved by adding a smallamount of AT functionalized CNTs. Additionally, the as-prepared CNTs-epoxy nanocomposites exhibited superiortribological properties with much lower frictional coefficients and wear rates compared to those of neat epoxy resin. Thewell dispersed AT-functionalized CNTs in epoxy matrix played an important role in enhancing the mechanical properties,as well as acting as a solid lubricant for improving the tribological performance of epoxy/CNTs nanocomposite.
