COMPOSITION AND METHOD OF MAKING A FERROFLUID WITH CHEMICAL STABILITY |
| 摘要 |
The invention relates to a composition and a process for producing a magnetic fluid comprising finely divided magnetic particles covered with at least one surfactant. A fluorocarbon-silane surface modifier is employed which is added to cover the free oxidizable exterior surface of the outer layer of the particles to increase the acid resistance of the colloid.
