Abstract: The electrochemical energy conversion system of the present disclosure includes an anode, a cathode, and an ion exchange membrane including a polymer having an aromatic polymer chain and an alkylated substrate including an alkyl chain, and at least one ionic group. The alkylated substrate is bound to at least one aromatic group in the polymer chain via Friedel-Crafts alkylation of the at least one aromatic group. The alkylation reaction utilizes a haloalkylated tertiary alcohol or a haloalkylated alkene as a precursor. In the presence of an acid catalyst, a carbocation is generated in the precursor which reacts with the aromatic rings of the polymer chain. The at least one ionic group is then replaced with a desired cationic or anionic group using a substitution reaction. The membranes exhibit advantageous stability achieved through a simplified and scalable reaction scheme.

Abstract: Methods for forming a polyelectrolyte complex (PEC) film are provided. In embodiments, the method comprises applying a potential between a working electrode and a counter electrode, the electrodes in contact with an aqueous polyelectrolyte solution characterized by a bulk pH. The aqueous polyelectrolyte solution comprises a pH sensitive PEC pair comprising an unmodified anionic polymer and a cationic species, an electrochemical pH agent other than water, and a salt. The applied potential induces an electrochemical reaction of the electrochemical pH agent to generate OH− or H+ at the working electrode without inducing water electrolysis in the aqueous polyelectrolyte solution, thereby forming a PEC film from the unmodified anionic polymer and the cationic species on a surface of the working electrode.
