The variation of the feature nmon-mon across different bins and for different situations is unremarkable [see Fig. ]. It is significantly high at near wall locations (bin 1), and progressively decreases as one moves away from the wall. This is an expected occurrence characterizing the decreases of the monomer density as one moves away from the grafting surface. PMETAC brush structure, we find a significant percentage contribution of nN-Cl for either of the situations. This implies that the chloride ion is still having a significantly large interaction with the part of the brushes that are in the brush-bulk interface. Therefore, in addition to probing the structure of the brushes in greater detail at the brush-bulk interface, one should also probe the distribution of the chloride ions (and their association with the brushes) at the brush-bulk interface.
