Abstract
Polyglycidyl methacrylate PGMAcoated soft magnetic carbonyl iron CI particles were fabricated by crosslinking PGMA with ethylene glycol dimethacrylate The synthesized core–shell structured CI/PGMA microspheres were characterized by scanning electron microscopy Fourier transform infrared spectroscopy and thermal gravimetric analysis The CI particles were confirmed to be coated well with PGMA A magnetorheological MR suspension was prepared based on the synthesized CI/PGMA particles dispersed in silicone oil and measured using a rotational rheometer at various magnetic field strengths The sedimentation property which was observed using a Turbiscan indicated better settling stability than the pure CI particlebased MR suspension
