The implicit-solvent simulations are symmetric regarding the positive and negative charge. However, as known from experiments, anions exhibit greater variety of interactions with ELPs than common cations. To investigate a broader range of interaction types and yet to stay consistent with the experiments, we varied the anion-polymer interaction strength while keeping the strength of cation-polymer interaction unchanged. The affinity of the ions to the polymer is controlled by ε cation and ε anion in the LJ potential acting between a monomer (regardless of its charge) and a cation, or an anion, respectively. The value of ε cation = 0.1 k B T is kept constant, corresponding to strongly hydrated cations. The value of ε anion varies between 0.1 k B T and 0.9 k B T, altering the value of the second virial coefficient of the interaction between anions and polymer. The actual B 2 values of the interactions employed in the simulations are summarized in Table .
