Thermally cross-linked poly(amide-imide) filter membrane |
| abstract |
Thermally cross-linked microporous polyamide-imide membranes having high chemical resistance and methods for making them are disclosed. The thermally cross-linked microporous membrane has an HFE bubble point from about 25 psi to about 200 psi and has an IP A flow-time from about 400 second to about 40,000 seconds. Another thermally cross- linked microporous polyamide-imide membrane includes a polyamide-imide polymer, wherein the membrane has a HFE bubble point from about 25 psi to about 200 psi. The membrane is asymmetric-and has a tight layer with a thickness of less than or equal to 10 microns. Filter and purification devices incorporating such devices are also disclosed. |
