20150014572 | MAGNETORHEOLOGICAL FLUID COMPOSITION AND METHOD FOR FORMING THE SAME - The present invention provides a magnetorheological fluid composition and method for forming the same. The magnetorheological fluid composition comprises a carrier fluid and a nano-magnetic-responsive composite dispersed uniformly in the carrier fluid. The nano-magnetic-responsive composite is formed by having carbonyl iron microparticles react with a grafting agent to form a modified carbonyl iron nanoparticles and blending the modified carbonyl iron nanoparticles with acid-treated graphene or carbon nanotubes. | 01-15-2015 |
