“…They have diameter of 3–7 nm, see Figure 1e. In order to promote dispersibility in water, FWCNTs were surface functionalized by oxygen containing groups (mostly ‐COOH, >C=O, and –OH), see Supporting Information 42. For simplicity, the functionalized nanotubes are subsequently still denoted as FWCNTs.…”

Mechanically excellent native cellulose nanofibers that are cleaved from plant cell walls have been modified by functionalized few-walled carbon nanotubes for hybrid nanofiber/nanotube aerogels. They show elastic mechanical behavior in combination with reversible electrical response under compression allowing responsive conductivity and pressure sensing. The concept combines wide availability of nanocellulosics and electrical functionality of carbon nanotubes synergistically.

“…The samples of MWCNTs were treated by a nitric acid solution for the removal of a catalyst and for the deposition of carboxyl groups (COOH) on the surface of MWCNTs, which increases the "solubility" of nanotubes in organic solvents [16]. The characteristics of MWCNTs were determined by helium pycnometry (Micro-Ultrapyc 1200e Quantachrome) and the lowtemperature adsorption of nitrogen (Nova 1200e, Quantachrome) (see the table).…”

A uniform distribution of carbone nanotubes in a polymer matrix is required for the fabrication of composite materials. Since carbon nanotubes for introduction into polymers are preliminarily dissolved in water or organic solvents, it is necessary to create a uniform stable dispersion of carbon nanotubes in solvents. It is shown in this work that the concentration of nanotubes is a critical parameter determining the stability and composition of a solution. The kinetics of agglomeration of multiwalled carbon nanotubes dispersed in chloroform by sonication has been studied using optical spectroscopy and dynamic light scattering. It has been shown that such solutions can be stable for a long time at nanotube concentrations below 0.01 wt %. The intense agglomeration and sedimentation of nanotubes have been observed in a solution with a higher concentration.

“…Oxidation of CNTs by strong acids is a well-known strategy to create functional groups like carboxylic (-COOH), carbonyl (-CO) and hydroxylic (-OH) [13][14][15][16][17][18][19]. This changes the reactivity of nanotubes and modifies the wetting characteristics, which would enrich their properties.…”
