Co-Poly(ionic liquid) Films via Anion Exchange for the Continuous Tunability of Ion Transport and Wettability.

ABSTRACT: This manuscript details a novel and simple approach to achieve surface-tethered co-poly(ionic liquid) (coPIL) films through the exchange of the resident anion of a poly(ionic liquid) (PIL) film with two or more anions. Initially, surface-tethered PIL films were prepared by the surface-initiated ring-opening metathesis polymerization of the ionic liquid monomer 3-[(bicyclo[2.2.1]hept-5-en-2-yl)methyl]-1,2-dimethylimidazol-3-ium hexafluorophosphate ([N₁-dMIm][PF₆]) whose PF₆ ^- anion was easily interchanged with aqueous solutions containing a binary mixture of the PF₆ ^- anion, along with perchlorate (ClO₄ ^-) or bis(fluorosulfonyl)imide (FSI^-) anions. The binary mole fraction of each anion in the
