Abstract
The present invention generally relates to polymeric membrane materials formed, at least in part, from monomeric material selected from 2,3,3,3-tetrafluoropropene (CF3CF=CH2, HF0-1234y0 or trans-1,3,3,3-tetrafluoropropene (CF3CH=CFH, HFO-1234ze), and to membrane preparations and uses thereof in water desalination, filtration, membrane distillation, pervaporation, and selective gas separation.
Claims15
A membrane comprising a polymer selected from the group consisting of a polymer comprising 2,3,3,3-tetrafluoropropene as a monomer unit of the polymer and a polymer comprising trans-1,3,3,3-tetrafluoropropene as a monomer unit of the polymer.
