  • Water treatment membrane and method of making water treatment membranes
    Patent number: 11383206
    Abstract: A water treatment membrane and method of making water treatment membranes includes an interfacially formed polyamide layer residing upon a microporous support film and having a plurality of graphene oxide quantum dots attached to an outer surface of the polyamide layer. The polyamide layer has a permeate flux and a salt rejection performance. The permeate flux is increased by the presence of the graphene oxide quantum dots attached to the outer surface of the polyamide.
    Type: Grant
