Asymmetric multifunctional heterogeneous membranes are demonstrated by combing a block copolymer polystyrene‐ block ‐poly( N , N ‐dimethylaminoethylmethacrylate) membrane with a track‐etched porous poly(ethylene terephthalate) membrane. This hybrid membrane is capable of integrating pH‐ and temperature‐cooperative high‐performance ionic rectification, highly efficient cation gating, and excellent stability and controllability, which allows broad application in biosensing, energy conversion, and filtration.
