Membrane separation technology can separate target substances without phase change under mild conditions,and has great application prospects in food,chemical and environmental fields.Stimulusresponsive polymers/inorganic nanoparticles are able to respond to a specific external stimulus;and integrating stimulus-responsive substances with membrane may improve its antifouling and self-cleaning performance,which provides new ideas for in situ control of membrane fouling and green cleaning.This review first briefly introduces the commonly-used responsive polymers/inorganic nanomaterials and the corresponding stimulus-response mechanisms,then focuses on the membrane preparation methods and application scenarios of antifouling membranes based on stimulus-response mechanisms,and finally presents an outlook on the challenges and future prospects of their industrial applications.
