This paper describes directions of realization of the multilevel modification principle in materials science and technology of polymer composite materials based on thermoplastics. It is shown that the introduction of nanoscale particles of different structures and production technologies into the composition of the composite makes it possible to transform the structure at various organization levels, which leads to the achievement of a synergistic effect of increasing the parameters of deformation-strength, tribotechnical characteristics and resistance to the action of thermal-oxidative medium. One of the perspective technologies of the nanomodifiers introduction into the composite material is the diffusion treatment of components and products in precursor solutions. Mixture of composite materials with increased parameters of performance characteristics for use in engineering, chemical and mineral resource industries have been developed.

There were studied mechanisms interfacial interactions in composite systems based on dispersed particles of polymer materials (polyolefins, polyamides, fluorcontaining polymers) and modifiers of various composition and structure in the combination process in the units with intense mechanical action. There were established the effects of formation of products of mechanochemical interaction of active centers of modifiers particles and radical fragments of macromolecules degradation. The obtained results allow changing the technological paradigm of the creation of high-strength and highly filled engineering nanocomposites based on high-molecular matrix.
