MODIFIED POLYAMIDE MEMBRANE |
摘要 |
A modified polyamide membrane and method for making and using the same. The present invention includes many embodiments including methods comprising contacting a polyamide membrane with certain modifiers, including but not limited to certain oxazoline and/or thiazoline- based compounds, derivatives and polymers thereof. In one embodiment, the surface of a polyamide membrane is coated with a solution including a polyoxazoline and optionally a polyalkylene oxide material, followed by optional heating. Preferred embodiments may exhibit improved performance, e.g. increased rejection of certain species, (e.g. sodium chloride and/or boric oxides such as boric acid or various borate salts), reduced fouling, improved antimicrobial properties, and/or improved storage stability. |
