ABSTRACT In this work, nanostructured composites in the form of polymer matrices with inclusions of magnetic particles were studied by the method of static scattering of laser radiation. The particles were embedded into polyvinyl alcohol and epoxy resin from magnetite -containing ferrofluid. It is shown that in a magnetic field they form a system of extended aggregates acting as light scatterers and established that optical technique based on this provides important information about the properties of such nanomaterial.

KEYWORDS nanocomposite, magnetite nanoparticles, ferrofluid, polymer matrix.
