Abstract

Epoxy-amine resin systems were reinforced with pristine and amino-functionalized multi-walled carbon nanotubes (MWNT) at loading concentrations up to 1 wt % using shear mixing as a dispersion method. It was found that nanocomposites containing fimctionalized MWNT exhibit significant reduction of macroscopic agglomeration in comparison to those containing pristine MWNT. Solvent uptake studies, performed to quantify adhesion of nanotubes to the matrix, suggest that amino-functionalized nanotubes achieve a more uniform dispersion and form covalent interactions with the polymer matrix. In addition, mechanical testing of the nanocomposites suggests marginal improvement of Young's modulus at low nanotube loading.
