Star polymer-assembled membranes for desalination and water treatment. |
초록 |
Star polymers possess unique three-dimensional globular architectures with multiple linear arms having the high density of active functional groups. We employed the star polymer as a new building block material to fabricate thin film composite (TFC) membranes for desalination and water treatment. We synthesized a star polymer with the high density of terminal amine groups via atomic transfer radical polymerization, followed by amine end-functionalization. The prepared amine-functionalized star polymers were assembled into TFC membranes via the interfacial polymerization process. The star polymer-assembled membranes exhibited nanofiltration and reverse osmosis grade separation performance with high water permeance and salt rejection as well as the excellent antifouling property. Star polymers provide a new material platform for the design of multifunctional films, coatings, surfaces and membranes for water, energy and environment applications. |
