Ultra-thin integral composite membrane |
摘要 |
An ultra-thin composite membrane is provided which includes a base material and an ion exchange resin. The base material is a membrane which is defined by a thickness of less than <DEL-S DATE="20010807" ID="DEL-S-00001">1 mil (0.025 mm)<DEL-E ID="DEL-S-00001"> <INS-S DATE="20010807" ID="INS-S-00001">0.8 mils <INS-E ID="INS-S-00001">and a microstructure characterized by node interconnected by fibrils, or a microstructure characterized by fibrils with no nodes present. The ion exchange resin substantially impregnates the membrane such that the membrane is essentially air impermeable.
