摘要：
Magneto-responsive polyaniline (PANI)-coated magnetic carbonyl iron (CI) microspheres were synthesised using a dispersion polymerisation process. The CI particles were initially modified using dopamine as a chemical grafting agent to strengthen the affinity between PANI and the CI particles. The surface morphology of the fabricated core-shell structured particles was confirmed by scanning electron microscopy. The chemical composition of the dopamine-modified CI particles was examined by X-ray energy dispersive spectroscopy, and the magnetic properties of the particles were analysed using a vibrating sample magnetometer. The magnetorheological (MR) characteristics of the CI-PANI particle-based MR fluid dispersed in silicone oil were measured using a rotational rheometer, which exhibited a typical liquid-like to solid-like phase transition. The sedimentation stability of the microspheres was analysed further using a Turbiscan apparatus with better dispersion stability than pure CI particles. (C) 2016 Elsevier B.V. All rights reserved.
