Influence of the structure of polytetrafluoroethylene-based nanocomposites on their tribotechnical characteristics

Results of investigation of the influence of the structure of nanocomposites based on polytetrafluoroethylene and fibrous aluminum- and magnesium-oxide nanopowders on their tribotechnical characteristics are presented. The basic regularities of structure formation in the studied polymer composite materials are established. The interrelation between the supramolecular composite structure and the nanofiller chemical nature, phase composition, and concentration is investigated. The structural transformations in the composites agrees well with the changes in their physicomechanical and tribotechnical characteristics. The most perfect supramolecular structure, which is characterized by the formation of uniformly shaped and sized spherulites evenly distributed in the matrix volume, corresponds to the best deformation-strength characteristics of the material and to decrease in its friction coefficient and wear.
