Abstract
Ultra-fine magnetic particles are difficult to be dispersed in lour bailing point solvents such as alcohol (C-1-C-4) and acetone. In this paper, we re port the preparation methods of several alcohol and acetone-based magnetic fluids. The stability of magnetic fluid depended on the HLB (hydrophile-lip ophile balance) of the solvent and alkyl chain lengths of organic layers. T he fluid was most stable only when the HLB value of surfactant and the solv ents are similar. (C) 1999 Published by Elsevier Science B.V. All rights re served.
