As mentioned above, in our previous articles, the mismatch of hydration strength ensures that the Cl -counterions are loosely attached to the PMETAC chains: this finding is also supported by the experiments. As a result, in the presence of a large electric field, due to the electrostatic effects, the Cl -ions move with a very large velocity from right to left. In standard electrophoretic problems, too, such counterion motion occurs; this results in the counterion cloud leaving the charged species (macromolecule or polymer chain, for example), and as a result, the charged species moves in a direction opposite to the motion of the counterions to avail a newer region of counterions. This ensures that the charged species (the macromolecule or the polymer chain) undergoes the expected electrophoretic motion. On the contrary, in the present case, the Cl -ions electric field, i.e., demonstrate their natural electrophoretic migration tendency, while for Case 2 (same condition as studied in this paper), we obtain the tilting and bending of the brushes in a direction that is against their standard electrophoretic migration direction (i.e., the antielectrophoretic behavior that we observe in our results). Also, the decrease in the brush height is much smaller for Case 2 as compared to Case 1 [see Fig. .
