Surface and structural characterization of multi-walled carbon nanotubes following different oxidative treatments
Kevin A. Wepasnick,Billy Smith,Kaitlin E. Schrote,Hannah K. Wilson,Stephen R. Diegelmann,D. Howard Fairbrother +5 more
TL;DR: In this article, six commonly used wet chemical oxidants were evaluated in terms of their effects on the surface chemistry and structure of MWCNTs using a combination of analytical techniques, including X-ray photoelectron spectroscopy (XPS) and energy dispersive spectrograph (EDX).

Chemical and structural characterization of carbon nanotube surfaces.
TL;DR: A critical review of the techniques used to explore the chemical and structural characteristics of CNTs modified by covalent surface modification strategies that involve the direct incorporation of specific elements and inorganic or organic functional groups into the graphene sidewalls is provided.
Sorption of aqueous Zn[II] and Cd[II] by multiwall carbon nanotubes: the relative roles of oxygen-containing functional groups and graphenic carbon.
Hyun-Hee Cho,Kevin A. Wepasnick,Billy Smith,Fazlullah Khan Bangash,D. Howard Fairbrother,William P. Ball +5 more
TL;DR: Exposure of multiwalled carbon nanotubes (MWCNTs) to oxidizing acids and other oxidants introduces oxygen-containing functional groups such as hydroxyl, carboxyl, and carbonyl groups onto the surface, which influences the sorption of aqueous zinc and cadmium on MWCNTs.

Colloidal Properties of Aqueous Suspensions of Acid-Treated, Multi-Walled Carbon Nanotubes
Billy Smith,Kevin A. Wepasnick,Kaitlin E. Schrote,A R Bertele,William P. Ball,Charles R. O'Melia,D. Howard Fairbrother +6 more
TL;DR: In this article, the authors studied the influence of pH and electrolytes on the colloidal stability of oxidized multiwalled carbon nanotubes (O-MWCNTs), prepared by refluxing pristine MWCNTs in nitric acid.

Influence of surface oxides on the colloidal stability of multi-walled carbon nanotubes: a structure-property relationship.
Billy Smith,Kevin A. Wepasnick,Kaitlin E. Schrote,Hyun-Hee Cho,William P. Ball,D. Howard Fairbrother +5 more
TL;DR: Quantitative relationships can be developed to rationalize the influence of surface chemistry on the behavior of nanomaterials in aquatic environments and reveal that carboxylic acid groups playing the most important role are highlighted.
