Surfactive stabilization of multi-walled carbon nanotube dispersions with dissolved humic substances
MA Chappell, AJ George, KM Dontsova, BE Porter… - Environmental …, 2009 - Elsevier
Soil humic substances (HS) stabilize carbon nanotube (CNT) dispersions, a mechanism we
hypothesized arose from the surfactive nature of HS. Experiments dispersing multi-walled
CNT in solutions of dissolved Aldrich humic acid (HA) or water-extractable Catlin soil HS
demonstrated enhanced stability at 150 and 300mg L− 1 added Aldrich HA and Catlin HS,
respectively, corresponding with decreased CNT mean particle diameter (MPD) and
polydispersivity (PD) of 250nm and 0.3 for Aldrich HA and 450nm and 0.35 for Catlin HS …
