“…A preparation method for individually dispersed SWNTs in both liquid and dried solid states was developed using triphenylene 23 derivatives. 107 On this basis, a highly concentrated solution of SWNTs (0.7-0.8%) was prepared, and also the SWNTs were well dispersed aer the addition of methanol (up to 70%) for a long time. These properties (redispersion ability and dispersion in the presence of organic solvent) were not observed in typical dispersing surfactants, such as SFBS and sodium cholate.…”

Contemporary methods for dispersion of carbon nanotubes in water and non-aqueous media are discussed. Most attention is paid to ultrasonic and plasma techniques and other physical techniques, as well as to the use of surfactants, functionalizing and debundling agents of distinct nature (elemental substances, metal and organic salts, mineral and organic acids, oxides, inorganic and organic peroxides, organic sulfonates, polymers, dyes, natural products, biomolecules, and coordination compounds). Special studies on CNTs solubilization are examined.

“…Similarly, the heights of certain UV‐visible absorbance peaks increase with increasing X ; this bulk technique was used to qualitatively monitor exfoliation during ultrasonication 16. The freeze‐drying of a dispersed sample followed by simple re‐dispersion is an interesting supplementary technique for characterizing dispersion quality; samples that display the same photoluminescence after freeze‐drying and re‐dispersion are indicative of small bundles or individually dispersed CNTs that are well stabilized against aggregation 13, 17, 18…”

Because of their unique mechanical, optical, thermal and electrical properties, carbon nanotubes (CNTs) form the basis for a wide variety of multifunctional devices and materials; many of these applications require that CNTs be dispersed and processed in liquids such as organic solvents, polymer melts or surfactant solutions. One of the most problematic issues affecting the CNT research community is the lack of standards and uniform characterization methods for CNT dispersion. A 2005 NASA‐NIST workshop aimed to address this issue and made a clear distinction between ‘nanodispersion’ of individual CNTs and ‘macrodispersion’ of CNT bundles. Unfortunately, this distinction has yet to percolate through the CNT dispersion literature. The present article seeks to elucidate and commend these concepts, identify the situations where this difference is most critical, note some scenarios where these concepts have been underutilized and posit experimental and computational characterization methods for quantifying the degree of nanodispersion. Particular attention is devoted to the controversial claims of complete nanodispersion and how such claims may be verified. Copyright © 2010 Society of Chemical Industry

“…In order to facilitate the dispersion of nanotubes in polar solvents, aromatic nature surfactants are used (e.g., octylphenoethoxylate, sodium dodecylbenzenesulfonate, amphilic compounds based on tri‐phenylene, etc.). They can attach more firmly to the nanotubes surface due to noncovalent interactions …”

Using the methods of infrared spectroscopy (IRS) and X-ray photoelectron spectroscopy (XPS), it was shown that short-term high-energy machining of detonation nanodiamonds (DND) leads to structural changes in the crystal structure and functional composition of the surface layer on particles. The possibility of spontaneous formation for stable colloidal systems with a narrow size distribution of mechanically activated DND in phenol-formaldehyde oligomers (PFO) was established. By molecular spectroscopy it was revealed that π ! π* interactions of the aromatic rings of PFO are caused by orientational phenomena as a result of hydrogen bonds between an activated DND surface and functional groups of PFO. The effect of DND concentration on the curing reaction parameters ofpsgr the phenolformaldehyde oligomer was determined by differential scanning calorimetry (DSC). The concentration effect of mechanically activated nanodiamonds on the physical and mechanical characteristics of a composite material based on phenol-formaldehyde binder and polyamide paper (Nomex) was studied.
