Mechanical properties of polymeric composites with carbon dioxide particles

Аннотация

Nanocomposites consisting of a polymethylmethacrylate or polystyrene matrix with embedded silicon dioxide nanoparticles surface-modified by silazanes have been prepared by melting technology. The influence of particles on viscoelastic properties of the nanocomposites has been studied using dynamic mechanical analysis. It has been revealed that the addition of 20 wt % of SiO₂ raises the flexural modulus of the nanocomposites by 30%.
