An ultra-thin anion exchange membrane incorporates functional additives to provide improved water management. Without the functional additives the ultra-thin membrane may have high cross-over and not be effective for many applications. A composite anion exchange membrane includes a porous scaffold support such as a porous polymer. The anion exchange polymer may be coupled to the porous scaffold, such as by being imbibed into the pores of the porous scaffold. The functional additives may contribute to increase water production, water retention, back-diffusion and reduce the gas crossover. A functional additive may include a reactive species, including a catalyst that reacts with oxygen or hydrogen, a plasticizer, a hygroscopic material and/or a radical scavenger.

In one aspect, separation media are described herein operable for removing one or more water contaminants, including NOM, fluorinated chemicals, and/or derivatives thereof. Briefly, a separation medium comprises a silica-containing granular support; and an oligomeric stationary phase forming a film on individual grains of the granular support. In some embodiments, the oligomeric stationary phase comprises oligomeric chains covalently bound to the individual grains.
