Method for making semipermeable polymer membranes |
| abstract |
A method for making a semi-permeable microporous polymer sheet, useful as a separation membrane or the like, comprising extruding a melt-blended mixture of a high-temperature thermoplastic polymer and a leachable glass to form sheet and then leaching the glass from the sheet to leave a microporous relict polymer network, wherein the permeability of the sheet is improved by plasma-etching the surface of the sheet before or after leaching. Hydrophilic or hydrophobic porous membranes may be provided. |
