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.
