Figure (a) shows the radial distribution functions (RDF) for NO - 3 , Cl -, Na + ions, and the oxygen atom of water (OW), relative to the charged groups of DCPAMs, specifically the nitrogen (N + ) ions of the B n -block, where n = 8. The analysis is carried out at an added salt concentration of 0.1 M, with 5 DCPAM chains solvated. In other words, the system under consideration consists of 30 Na + , 30 NO - 3 , and 60 Cl -ions. The RDF curves show distinct behaviors: (i) The peaks for OW, NO - 3 , and Cl -ions are at r ≈ 0.46, 0.464, and 0.494 nm, respectively, while Na + ions are notably absent within this region. For NO - 3 ions, the distance is calculated relative to the nitrogen atom at the center of the ion, which is symmetrically surrounded by three oxygen atoms (see Fig. ). The attraction of NO - 3 and Cl -ions to positively charged sites on the DC-PAM chains is attributed to Coulombic interactions. The differences between peak height for NO - 3 and Cl -arise from the normalization of each curve to the number density of the respective species. This suggests that for a similar distribution of NO - 3 and Cl -, the peak height of Cl -should theoretically be half that of NO - 3 . However, the highest RDF peak height of NO - 3 (≈ 19) is more than twice that of Cl -(≈ 5.8), suggesting stronger adsorption of NO - 3 to the B-blocks. (ii) A secondary peak accompanied by a satellite curve extends to 2 nm, representing longer-range electrostatic correlations. In this region, Na + ions are also present, but their density remains lower than NO - 3 and Cl -ions. Regardless of the m : n ratio and salt concentration, water molecules consistently orient with their oxygen atoms facing toward the nitrogen atom of the B-block (see Fig. of Supplementary Material (SM)).
