The unique supramolecular structure and dynamic properties of polyrotaxane have attracted great attention from scientists. It also has important application potential in membrane field, and there have been a series of reports. This paper introduced the development of molecular machine, membrane separation technology, the classification and fabrication of PR-based membranes. The latest background and application progress of PR-based membranes in membrane fields were also presented, including antifouling property, adsorption, ionic conduction, oil/water separation and so on. The separation performance and mechanism of PR-based membranes were discussed. The function of the dynamic structure in membrane and membrane separation were also discussed. The combination of PR and polymers membrane was beneficial for the improvement of membrane properties such as hydrophilicity, water flux, rejection rate antifouling property, adsorption performance, conductivity and mechanical performance. At the end, the challenges and future prospective of PR in membrane field were proposed.
