prepared well-dispersed silica-poly(methyl methacrylate) (SiO2-PMMA) nanoparticles by a suspension-dispersion-polymerization technique in an aqueous system. Subsequently, SiO2-PMMA nanoparticles were induced into PVC matrix, and results showed that the heat resistance, elongation at break, and tensile strength of PVC/SiO2 composites were significantly improved. Also, Peng et al. prepared natural rubber/silica nanocomposites (NR/SiO2) [10] and natural rubber/multiwalled carbon nanotubes composite [11] combining self-assembly and latex-compounding techniques. Obtained nanocomposites were perfectly strengthened, with increased thermal resistance and mechanical properties.
