Counterion concentration distribution around PAMAM and PA/PC bilayer6 of similar charge density (0.19 C m–2 for PAMAM and 0.21 C m–2 for PA/PC). The number of counterions present in the PAMAM system is 30 Cl–, while for PA/PC, it is 48 Na+. The distribution was averaged using a floating window with a 0.2 nm bin size and a 0.01 nm increasing step.
