| titleOfInvention | Polymer membrane containing magnetic ultrafine particle and production thereof |
| abstract | PURPOSE: To produce the titled polymer membrane having excellent susceptibility, by bringing an aq. soln. of a specified iron salt and an aq. alkali soln. into contact with each other through a porous gel membrane of a hydrophilic polymer to disperse and incorporate magnetite in the gel membrane. n CONSTITUTION: A porous gel membrane 1 having a thickness of 10W300μm and composed of a hydrophilic polymer is held between two cells 2. An aq. soln. of 0.05W0.1mol% of a ferric salt (e.g., FeCl 2 or FeSO 4 ) is introduced into one of the cells 2, and an aq. soln of 0.8W1mol% of an alkaline substance (e.g., an aq. soln. of NH 3 , KOH, LiOH, etc.) is introduced into the other cell. Both aq. soln. are brought into contact with each other through the membrane 1. While the soln. is stirred by bars 4 by driving magnetic stirrers 3, they are reacted at 40W70°C for 1W2hr to form magnetic ultrafine particles having a particle diameter of 3W30nm and composed of magnetite (Fe 3 O 4 ) and immediately disperse and incorporate them in the membrane 1. n COPYRIGHT: (C)1987,JPO&Japio |
