ABSTRACT:
Membranes as well as a methods of treating membranes are disclosed. The method of treating a membrane includes contacting the membrane with a first solvent, contacting the membrane with an inert solvent, and contacting the membrane with an amine reactive compound. The first solvent includes a solvent having a Hansen solubility parameter in a range from about 10.0 to about 18. The membrane includes a polymer having an amine group.
