On page 2467, Haiqing Lin and colleagues provide a timely review of various strategies adopted to molecularly engineer polymer membranes for H₂/CO₂ separation, enabling cost‐effective H₂ purification and CO₂ capture. The authors exhaustively reviewe functional polymers and engineered polymers by cross‐linking, thermal treatment, thermal rearrangement, carbonization, and blending with polymers and size‐sieving or H₂‐sorptive nano‐fillers. These emerging polymers are benchmarked with state‐of‐the‐art commercial membranes to demonstrate their potential. (DOI: 10.1002/pol.20200220)
