RESISTANT POLYMER NANOCOMPOSITES’ DEVELOPMENT AND INVESTIGATION

Introduction. The advanced technology development demands higher requirements to the physicomechanical characteristics of the polymer composite materials (PCM) widely used in general and special purpose products such as in transport and road-building. This determines the relevance and significance of the new polymer nanocomposites development on the tribotechnical purpose with high physic-mechanical and tribotechnical characteristics. Materials and methods. The problem mentioned above is solved by means of the structural modification’s methods of the PCM polymer matrix and the technological process optimization of the composite materials’ synthesis. One of the structural modification advanced methods is the polymer matrix charging with different fillers’ types, particularly, disperse and fiber ones, and in recent years – ultradispersed and nanodimensional fillers. Results. The composite materials with nanodispersed fillers feature the properties significantly different from those of the materials with microand macrodispersed particles because of the high surface activity of nanodimensional particles’ fillers. Discussion and conclusion. The research deals with the development results and polymer nanocomposites’ investigation with polydispersed and nanodimensional fillers, their influence upon the structure and wear-resistance of the polymer composite materials based on polytetrafluorethylene.
