Surface modified magnetic particles were compositely coated by transition liquid and then dispersed in 2-methyl silicon oil to prepare silicon-oil-based magnetic liquid.

Compared with traditional water-based and kerosene-based magnetic liquid,silicon-oil-based magnetic liquid has the features of stable chemical property,good heat resistance and little change of viscosity with temperature.

Silicon-oil-based magnetic liquid is a kind of functional liquid material.

With a research background of magnetic liquid in fluid sealing application, preparation method of PFPE oil-based magnetic liquid and rolling axis, sliding axis magnetic liquid sealing experiment device used in fluid sealing are studied in this thesis.

Because of its good heat-resisting capability,silicon-oil-based magnetic fluid is drawing more and more people s attention.

The study of recent progress in research into magnetoviscous effect of ferrofluids;

Using magneto-optical effect to study the chain aggregation behavior of ferrofluids under an external magnetic field

The magnetic behavior of CuFe_2O_4 nanoparticles prepared by co-precipitation and their self- formed ferrofluids is measured at room temperature.
