Abstract
| - A mathematical problem is formulated and numerically solved for addressing the electric field and ionicconcentration distributions developing around the three-phase contact line during the Langmuir−Blodgettdeposition of charged monolayers. Compared to a previous paper dealing with the same effect (J. Phys.Chem. B2004, 108, 13449), the present analysis is not restricted to the case of low deposition rates and smallconcentration changes. The obtained results show that, for sufficiently high deposition rates, the subphasecomposition substantially changes in the immediate vicinity of the three-phase contact line. It is shown thatthe predicted changes in the subphase composition can drastically affect the adhesion work and the dynamiccontact angle. On this basis, the influence of the concentration polarization effect on meniscus behavior isdiscussed.
