“…The CMC values for two series of C n B and C n TAC were determined by conductivity measurements, some of which were in agreement with the literature values [13,14,18,19]. The relationships between the CMC and alkyl chain length are shown in Fig.…”

Surface-active properties of cleavable surfactants with a betaine ester group-(n-alkyloxycarbonylmethyl)trimethylammonium chlorides, used as separation reagents-were investigated. Critical micelle concentrations, dispersing powers, and foaming powers were comparable to those of alkyltrimethylammonium chlorides with the same total number of carbon atoms. On the other hand, the solubilities of the four hydrophobic dyes N,N-dimethyl-3-nitroaniline, naphthalene, pyrene, and oil orange SS in the former surfactant solutions were equal to or slightly smaller than those in the solutions of the latter surfactants with the same alkyl chain length. The alkali hydrolysis yields of the formers approached 100% in aqueous buffer solution at pH 10 and 25°C within 10 min, and the yield at pH 9 was dependent on the alkyl chain length. This type of surfactant was also found to be as an efficient separation reagent which disperses carbon black and solubilizes the above dyes into aqueous neutral solution and then separates them instantaneously and almost perfectly as precipitates when a small excess of NaOH is added.

“…A He, Ne, Ar ion laser was the light source and the wavelength of the laser light was 639 nm. The detection angle was 90 • and the temperature was set at 23 • C. Further, by using diluted carbon solvent dispersions (20 mg L −1 ), multiple scattering effects were avoided and the autocorrelation function was measured correctly [20].…”

“…Recently, most studies in this field are concerned with adsorption from an aqueous solution. 9,11,12,14,15 The amount of surfactant that is applied to prepare the dispersion may influence not only the state of CB dispersion but also some other properties of the dispersion. The literature provides useful data concerning the influences of dispersants on the viscosity and on the colorimetric properties of concentrated CB suspensions.…”

Influence of dispersing additives on the conductivity of carbon black pigment dispersion

et al. 2011

The influence of dispersing additives on the electrical conductivity of carbon black pigments dispersed in an organic medium was studied. Two dispersing additives were examined in combination with two different carbon blacks, a conductive carbon black and a nonconductive one. These carbon blacks differ in the size of their aggregates and in the amounts of surface oxygen groups. Both of the additives form a monolayer when adsorbed on either of the pigment surfaces. FTIR studies showed that chemical bonding of one of the additives on the surfaces of both pigments had occurred. Conductivity decreases with increasing additive concentration, but in the case of the chemically bonded additive, the conductivity of the dispersion remained high even at higher additive loadings. This study helps in understanding the effects such additives have on the specific conductivity of composite materials that contain dispersed carbon black pigment particles.
