Summary
The potential for stabilizing aqueous dispersions of carbon nanotubes (CNTs) utilizing phenol-formaldehyde resin (PFR) and aminocumulene (AC) is proven. The preliminary oxidation of CNTs contributes to their larger solubility within the presence of those stabilizing brokers. The focus of pristine and oxidized CNTs in weakly alkaline options containing 2.5 g/L of PFR is 3.0 and 11.4 g/L, respectively. AC promotes the formation of steady dispersions in acidic media with the concentrations of pristine and oxidized CNTs, respectively, 3.3 and 20.4 g/L. A lower within the efficient sizes of agglomerates of each pristine and oxidized CNTs within the presence of PFR and AC has been proven by dynamic mild scattering methodology. Based on TG/DSC evaluation and Raman spectroscopy information, it was concluded that the oxygen-containing teams of oxidized CNTs work together with the surfactants used. Schemes for the formation of hydrogen and chemical bonds between CNTs and PFR or AС have been proposed, which made it potential to clarify the impact of dispersion.
