Abstract
In one embodiment, a method of modifying a surface of a membrane includes exposing the surface to an impinging atmospheric pressure plasma source to produce an activated surface, and exposing the activated surface to a solution including a vinyl monomer. In another embodiment, a method of manufacturing a desalination membrane includes treating a surface of the membrane with an impinging atmospheric plasma source for an optimal period of time and rf power, and exposing the surface to an aqueous solution containing a vinyl monomer. In another embodiment, an apparatus includes a membrane having a surface, and polymer chains terminally grafted onto the surface of the membrane.
