The area of research of our laboratory is development of technologies of production
of finely dispersed and low-porous magnetic powders and composite materials.

Historically, the area of interests of the laboratory includes synthesis and applications of magnetic powders. Along with being utilized in various compositions, such materials may be used as:
- components of particulates to be employed in electromagnetic testing;
- magnetocontrollable high-porous hydrophobic adsorbents in purification systems for removing oily contaminants from water;
- magnetic fillers of printing inks with a broad spectrum of colors for protecting security papers against forgery;
- selective magnetocontrollable adsorbents in the medical field;
- components of oil suspensions for lubricating cutting tools in high-speed metalworking;
- magnetic fillers of one-component toners in copying machines and laser printers;
- fillers of paints and varnishes with radar-absorbent and radar-reflecting properties to protect the body, buildings, and equipment against SHF-radiation.

Elastomer deforming in a non-uniform magnetic field

The research directions of the laboratory are:
- synthesis methods of magnetorheological suspensions to be used in damping units and magnetic clutches;
- synthesis of specialized magnetic liquid materials for utilization in damping devices used on flying machines.
Another important area of our scientific research is technological development and study of magnetic elastomers, also known as ‘magnetorheological elastomers’, ‘magnetoactive elastomers’, ‘magnetocontrollable elastomers’, ‘magnetic gels’, etc. Such materials are comprised of an elastic polymer matrix, typically based on silicone resin, and magnetic filler, for which carbonyl iron or NdFeB-alloy powders, or their mixtures, are used.
As has been found out, magnetic elastomers exhibit the following properties:
- magnetorheological effect;
- magnetodeformation;
- magnetostriction;
- magnetoresistivity;
- (magneto)piezoresistive effect;
- shape memory in magnetic fields;
- magnetoelectric effect;
- variation of wetting angle in magnetic fields;
- magnetoelectric effect;
- piezoelectric effect.
