The formation of free ions and electrophoretic mobility of Ag and Au nanoparticles in n-hexadecane–chloroform mixtures at low concentrations of AOT

Abstract

<p>The electrophoretic mobility of Ag and Au nanoparticles in <italic>n</italic>-hexadecane–chloroform mixtures was studied as a function of the chloroform content (from 0 to 100 vol%).</p>

Electrophoretic mobility and stability of SiO2 nanoparticles in the solutions of AOT in n‐hexadecane‐chloroform mixtures

“…As shown in Ref. [17], in the region of low AOT concentrations the carriers of free charge are solvated АОТ – and AOTNa 2+ ions. In this connection, initial recharge of the surface in the case of small AOT concentration may be explained by the overequivalent adsorption of AOTNa 2+ ions on the hydrophilic surface of SiO 2 .…”

“…The dynamic viscosity and dielectric permittivity of individual solvents and their mixtures were measured by us previously [17]; these values were used to calculate the hydrodynamic radius, electrophoretic mobility, and zeta‐potential.…”

“…Previously, we established the fact of a substantial increase in the electrophoretic mobility of the nanoparticles of Ag, Au [17], and SiO 2 [18] in the solutions of AOT in saturated hydrocarbons in the presence of chloroform. In Ref.…”

Structure and conductivity of AOT solutions in n‐hexadecane‐chloroform mixtures

“…The increase in conductivity is accompanied by a growth of electrophoretic mobility. In our previous work [35], the nature of free charge carriers at low AOT concentrations was studied.…”
