Physically reinforced structured organic film (SOF) anion exchange membranes (AEMs)

A structured organic film (SOF) composite, comprising:

• a first domain comprising a first composition;
• and
• a second domain comprising a second composition and incorporated into the first domain;
• and wherein:
• the first composition comprises a plurality of segments, and a plurality of linkers, wherein at least one of the plurality of linkers connects at least one of the plurality of segments;
• and
• the second composition comprises a polymer additive comprising poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene).

A structured organic film (SOF) composite, comprising:
