Abstract :
[en] Silica nanoparticles with average diameters of 12nm are grafted with PBMA-b-PMMA double shells through typical ATRP from a Si12-g-(PBMA)Br macroinitiator using 2-BriB as the initiator. A commercially available PMMA homopolymer is used for the preparation of composites with unmodified, silane-modified and double-shell-modified silica particles. Good mechanical properties are obtained for silica double shell containing systems. The silica content in double shell particle systems is varied from 0 to 2.5 wt%. A significant improvement in impact properties is observed. The surface-modified silica particles are characterized by ATR-FTIR, NMR, GPC, and thermal analysis. TEM analysis is used to analyze the nature of dispersion of particles in the composites.
