2results about How to "Good desalination effect" patented technology

A long-lasting antifouling polyamide reverse osmosis membrane, its preparation method, and its applications are disclosed, belonging to the field of membrane separation technology. The membrane comprises a porous support layer and a polyamide selective layer on its surface. The polyamide selective layer is covalently grafted with monoamine-terminated hyperbranched polyglycerol. The monoamine-terminated hyperbranched polyglycerol is grafted into the polyamide network through the reaction of its terminal primary amine groups with acyl chloride monomers during interfacial polymerization. This enriches the multi-hydroxyl branched structure of the hyperbranched polyglycerol on the membrane surface, forming a stable hydrophilic antifouling structure. The aforementioned long-lasting antifouling polyamide reverse osmosis membrane, its preparation method, and its applications result in a membrane with long-lasting and stable antifouling performance, strong hydrophilicity, and a simple preparation process, making it easy to industrialize.
