Polymer coated hydrolyzed membrane |
| abstract |
A method of forming a polymer coated hydrolyzed membrane includes forming a membrane from a first hydrophilic polymer by immersion precipitation, coating the membrane with a thin layer of a second hydrophilic polymer more pH tolerant than the first hydrophilic polymer to form a dense rejection layer, and exposing the coated membrane to a high pH solution thereby forming a hydrolyzed ultrafiltration membrane. A polymer coated hydrolyzed membrane includes a porous membrane formed from a first hydrophilic polymer by immersion precipitation and from 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. |
