Abstract
Magnetorheological (MR) fluids, dispersions of magnetically soft particles in fluids (gases, liquids, or semi-solids such as greases), are disclosed. The present invention uses the initial steps of a sol-gel process to assist in preparation of MR fluids that have significantly enhanced stability and redispersibility, without the use of ceramic particles such as silica or bridging polymers such as PVP.
Claims11
An magnetorheological fluid comprising particles of a soft magnetic material, a sol-gel precursor and a carrier liquid, said sol-gel precursor being capable of forming a bond with said particle surface.
