Electroosmotic Flow in Mixed Polymer Brush-Grafted Nanochannels

Mixed polymer brush-grafted nanochannels—where two distinct species of polymers are alternately grafted on the inner surface of nanochannels—are an interesting class of nanostructured hybrid materials. By using a coarse-grained molecular dynamics simulation method, we are able to simulate the electrokinetic transport dynamics of the fluid in such nanochannels as well as the conformational behav...

Mesoscopic simulations of electroosmotic flow and electrophoresis in nanochannels

We present dissipative particle (DPD) simulations of electrolyte flow in nanochannels for varying salt concentration and surface slip conditions. First, a method is presented by which the slip length δ Β at the channel boundaries can be tuned systematically from negative to infinity by introducing suitable wall-fluid friction forces. Using this method, we study electroosmotic flow (EOF) in nano...

High-ionic-strength electroosmotic flows in uncharged hydrophobic nanochannels.

We report molecular dynamics simulation results of high-ionic-strength electroosmotic flows inside uncharged nanochannels. The possibility of this unusual electrokinetic phenomenon has been discussed by Dukhin et al. [A. Dukhin, S. Dukhin, P. Goetz, Langmuir 21 (2005) 9990]. Our computed velocity profiles clearly indicate the presence of a net flow with a maximum velocity around 2 m/s. We found...
