Abstract:
The present invention provides membranes having a coating layer comprising cellulose or cellulose derivative and a porous support comprising nanofibers prepared by a process of coating a solution comprising cellulose or a cellulose derivative dissolved in an ionic liquid on to a porous support layer. The present invention is useful for providing improved water flux and high rejection rates for oil/water emulsions. The present invention also provides fluid separation systems in UF, NF, RO and FO, incorporating membranes of the present invention.
