Structure and thermodeformation properties of polymer–magnetite hybrid composites

  • Published:
Materials Science Aims and scope

We have studied the structure, microhardness, and thermomechanical properties of poly(styrenebutylacrylate)– magnetite hybrid composites, obtained by the method of suspension polymerization. We have established that composite grains are not susceptible to aggregation and have a spherical shape. By means of Raman spectroscopy, we have detected that, in the course of synthesis of a hybrid composite, simultaneously with the encapsulation of magnetite particles by polymeric shells, magnetite adsorption on the surface of composite grains takes place. We have also found the optimal interval of magnetite content (6.3 to 9.0 %) that provides the compaction of composites and enhancement of their mechanical strength as well as the temperatures of vitrification and flow.
