摘要: Abstract The soft magnetic composite of reduced iron particles encapsulated with polysiloxane shell was prepared by hydrolysis–condensation polymerization tetraethylorthosilicate (TEOS) on the surface particles. structure, morphology, properties, and chemical stability coated were studied. thickness about 60 nm according to results transmission electron microscopy (TEM) laser particle size analysis, while mean diameter 4.45 μm. composites greatly improved, though its properties declined a little. However, are still useful in MR fluids as much better than other like Fe 3 O 4 , etc.
