Figure S1 Raman spectra of as-received HiPco SWNTs (blue line) and SWNTs after chemical
treatment with sodium hydroxide / ethanol solution (red line). The Raman spectra were recorded
at an excitation wavelength of 633 nm.
Transmission electron microscopy
Figure S2 Transmission electron micrographs (JEOL-JEM 3010) of the P2 SWNTs subjected to chemical treatment by NaOH / ethanol.
Tensile testing
Figure S3 Average stress-strain curves for neat epoxy and epoxy-treated SWNT composites.
