Nanosilica filled polypropylene nanocomposites

Embedded precipitated nanosilica enhances stiffening, reinforcing and toughening of PP nanocomposites at lower concentration as fumed nanosilica. By grafting with polymers such as styrene, methyl methacrylate, butyl acrylate, and ethyl acrylate, the efficiency in the composites mechanical properties is increased depending on the grafting polymer used.  

Low nanoparticle-loaded polymer composites with improved mechanical performance can be prepared by a conventional melt blending technique in which the nanoparticles are chemically pregrafted by diglycidyl ether of
