Solvent-dispersed single-walled nanotubes (SWNTs) are incorporated into epoxy matrices, followed by evaporation of the solvent before curing. The effect of solvent choice in thermal and mechanical properties of the resulting nanocomposites is evaluated using N-methyl pyrrolidone and dimethyl formamide. In this study, fluorescence is used as the tool to monitor the dispersions of SWNTs in the solvent and epoxy matrix. This study also compares the thermal and mechanical properties of these epoxy nanocomposites with a nanotube loading ranging from 0.001-0.01 wt. %. The presence of residual solvent in the epoxy composites is determined by thermogravimetric (TGA) analysis. Thermo-mechanical properties of the resulting epoxy nanocomposites are determined using dynamic mechanical analysis and differential scanning calorimetry.
