Microporous membrane, method of manufacture, and method of use |
摘要 |
Microporous membranes having positive zeta potentials in alkaline pH are provided by radiation grafting diallyldimenthylammonium dimethyl ammonium chloride to the surraces of a microporous, polyamide membrane using ionizing radiation. The membranes have particular use in microelectronics manufacture where quick rinse up times with ultrapure water are required.
