A bioinspired multifunctional heterogeneous membrane composed of a block copolymer (PS‐ b ‐P4VP) membrane and a porous anodic alumina membrane is fabricated. The ionic rectification is so strong that the maximum ratio is ≈489, and the chemical actuation of the anion or cation gate from the “OFF” to the “ON” state promotes a 98.5% increase in the channel conductance.
