Summary: | The invention belongs to the technical field of ion exchange membranes, and particularly relates to anti-swelling amphoteric ion exchange resin, a preparation method, an ion exchange membrane and application. The invention provides anti-swelling amphoteric ion exchange resin, the structure of which is shown in the specification, x, y and z are positive integers of 1-200, m is an integer of 0-4, n is an integer of 0-3, and l is an integer of 0-2. The perfluoro main chain in the resin can improve the chemical stability of the resin, and the hydrophilic long side chain structure is beneficial to microphase separation, construction of an ion channel and improvement of proton conductivity. Besides, the quaternary amination group and the sulfonic acid group in the resin jointly form the amphoteric ion exchange resin, and the water absorption capacity of the sulfonic acid group is weakened due to mutual attraction of static electricity between positive and negative ions, so that the amphoteric ion exchange membrane |
