<p>Disclosed is a composition for forming or treating reverse osmosis (RO), forward osmosis (FO), microfiltration (MF), or nanofiltration (NF) membranes, which includes a stable liquid blend of two of the following polymers: an oxygen polymer, a nitrogen polymer, and a sulfur polymer, where each polymer in a blend have matched solubility parameters; provided, that a nitrogen polymer can be in the form of a powder; where the weight ratio of polymers in each blend can range from 1:99 to 99:1; where each polymer optionally can be halogenated; where any polymer can be dispersed in a solvent for forming the blend.</p> |
