(a) The possible distances between two [CMIM]Cl molecules in the 4 × 4 × 1 cell simulated system; (b) the optimal chain grafting positions of the [CMIM]Cl molecules at 50% surface coverage. The color code is as follows: the black indicates the [CMIM]Cl molecule’s positions; the blue indicates the DA molecule’s positions; and the gray indicates the Si substrate.
