Production of membranes |
| abstract |
A method of producing a porous membrane by gelation in a non-solvent medium of a solution of an aromatic ether ketone polymer in a strong acid which is substantially non-sulphonating to the polymer is characterised by the step of including a dissolved polymer in the gelation medium. The method allows the fabrication of membranes with pore sizes in the nanofiltration and low-ultrafiltration range having sufficient permeability for industrial and commercial application. |
