HYBROLIZED MEMBRANE COVERED WITH POLYMER. |
| abstract |
One method of forming a polymer-coated hydrolyzed membrane includes the formation of a membrane from a first hydrophilic polymer by immersion precipitation, the coating of the membrane with a thin layer of a second hydrophilic polymer more pH tolerant than the first polymer. hydrophilic to form a dense rejection layer, and exposure of the coated membrane to a high pH solution to thereby form a hydrolyzed ultrafiltration membrane. A polymer-coated hydrolyzed membrane includes a porous membrane formed from a first hydrophilic polymer by immersion precipitation and hydrolysis, and a dense rejection layer applied to the membrane and formed from a second hydrophilic polymer more pH tolerant than the first hydrophilic polymer. |
