Abstract: Nanocomposites based on SiO₂ nanoparticles dispersed in a PMMA matrix have been successfully prepared and submitted to tribological tests and c₁₁ measurements by Brillouin spectroscopy, so that to explore the elastic and wear behaviour of the material compared to pure PMMA. We show that the elastic constant and the stick-slip may be clearly different depending on the rate and the chemical bonding treatment of the nanoparticles. Correlation between these parameters is also discussed.

Keywords: nanocomposites; polymer-matrix composites; PMCs; friction; wear; mechanical properties; tribology; Brillouin spectroscopy; elastic constant; PMMA; silica; SiO2 nanoparticles; silanisation; stick-slip; nanotechnology; chemical bonding treatment.
