PROTEIN-Fe MR FLUID AND ITS PROPERTIES

Abstract

The MRF consisted of protein-Fe particles prepared by micro emulsion technique has been studied. The process of protein-Fe preparation and its characterization with XRD, SEM and IR analysis are reported. The magnetorheological and temperature effects, as well as sedimentation stability of protein-Fe MRF have been investigated. The results show that the protein-Fe particles are composite of crystalline α-Fe coated with non-crystalline protein. The protein-Fe MR fluid has strong magnetorhological effect, while its sedimentation stability is much improved comparing to that of carbonyl iron MRF.
