Cross Linking Treatment of Polymer Membranes |
摘要 |
Methods of forming a hydrophilic porous polymeric membrane which include preparing a porous polymeric membrane from a polymer blend which typically contains a hydrophobic non crosslinkable component (e.g. PVdF) and a component which is cross-linkable (for instance, PVP) and treating said porous polymeric membrane under cross linking conditions to produce a modified membrane with greatly improved water permeability and hydrophilic stability. Cross linking condition include chemical (e.g. peroxodisulfate species), thermal or radiation and/or combinations thereof. Non cross linked material may be washed out if desired.
