Process for surface modifying a microporous membrane |
摘要 |
A process for surface modifying skinless hydrophilic microporous membrane having an internal microstructure throughout said membrane and a surface modifying amount of surface modifying agent bound thereto without substantial pore reduction of pore blockage involves the steps of providing a dope solution of a membrane forming polymer in a solvent system comprising a mixture of at least one solvent and one non-solvent for the polymer, and a membrane surface modifying agent, and combining said dope solution with sufficient additional non-solvent for the polymer to precipitate said membrane from said dope solution.
