Selectively permeable polymeric membrane

A method of making a dehydration membrane comprising:

• curing an aqueous mixture that is coated onto a porous support;
• wherein the aqueous mixture that is coated onto the porous support is dried at a temperature of 60° C. to 100° C. for about 30 seconds to about 3 hours;
• wherein the porous support is coated with the aqueous mixture by applying the aqueous mixture to the porous support, and repeating as necessary to achieve a layer of coating having a thickness of about 100 nm to about 10000 nm;
• and
• wherein the aqueous mixture is formed by mixing a PEBA, a PDADMA, a PACD, a PSS, or a combination thereof, in an aqueous liquid.
