Investigation of physical-mechanical and tribological properties of suspensions of nanoparticles based on polyethylsiloxane liquid

The study of the physical-mechanical properties of suspensions of silica dioxide nanoparticles and fullerenes in polyethylsiloxane liquid was carried out. The shear modulus and effective viscosity of nanosuspensions were determined by the acoustical resonance method, the coefficient of friction with the base polyethylsiloxane lubricant and modified lubricants was determined, and an improvement of the tribological properties of the synthesized suspensions was shown due to increasing the strength of the lubricating film.
