Abstract
The solution method was used to create polysulfone/carbonnanotubes composites. The effect of three solvents (NMP, DMF, and THF),treatments (nitric acid and ethanol) and surfactants (ODA and OCA) on CNT/solvent stability was investigated. NMP and DMF resulted in improved stabilitycompared to THF, and all CNT treatments improved stability. Four compositeswere produced with CNT loadings of 0–5 wt%: as-received CNT and nitric acidtreated in THF, as-received CNT and OCA surfactant CNT in NMP. Optical, TEM,and electrical percolation measurements confirmed the role of CNT/solvent stabilityon the final composite dispersion. Tensile testing and thermal analysis confirmed thepresence of residual solvent in all samples.
