Then, we probed the influence of defects on electrolyte intrusion. Our simulations in the osmotic ensemble reveal that the alchemical work associated with electrolyte intrusion is similar to that computed in defect-free zeolites, and that the probability of electrolyte intrusion is very low. Consequently, silanol defects may not explain electrolyte intrusion in the approximation of our force field and classical simulations. The non-penetration of electrolyte observed in our simulations is consistent with experimental reporting, with water as the only species intruded in the chabazite at the intrusion pressure. The intrusion of electrolyte occurs at several order of magnitudes higher than the intrusion pressure and our simulations may not grasp this phenomenon: our forcefield describing the "rigid host" framework within the Kiselev approximation is specifically tailored to reproduce the intrusion of TIP4P water in silicalite-1 and electrolyte ions are simply described by charged beads ignored polarizability or charge transfer. The present study shows, in any case, that the attractive nature of the defects does not compensate the thermodynamic cost of desolvation of the ions from the bulk electrolyte. While it could be possible with defects of a stronger nature, they would then turn the zeolite hydrophilic overall.
