Polyethersulfone hollow fiber intelligent membrane with pH sensitivity as well as preparation method and application thereof

The invention relates to a polyether sulphone hollow intelligent fibrous membrane with pH sensitivity, a method for preparing the same and application of the fibrous membrane. The method is characterized in that 8 to 24 weight portions of acrylonitrile, 5 to 18 weight portions of crylic acid, 70 to 85 weight portions of a solvent and 0.1 to 0.5 weight portion of an evocating agent are added into a reaction kettle with a stirrer, a thermometer and a condenser; under stirring, the mixture reacts for 8 to 24 hours at a temperature of between 55 and 70 DEG C to obtain an acrylonitrile-crylic acid copolymer solution; and 10 to 28 weight portions of polyether sulphone, 70 to 85 weight portions of a solvent and 1.5 to 6 weight portions of an additive are put into a vessel and dissolved for 2 to 24 hours at a temperature of between 75 and 95 DEG C under stirring to prepare a polyether sulphone solution, and 0.2 to 0.6 weight portion of the synthetic copolymer polyether sulphone solution is added into the prepared pol
