The reinforcement and toughening effects of polystyrene radiation grafted silica nanoparticles (Si O2 - g - PS) on polypropylene (PP) were reported. The mechanical properties of these composites were also studied from the viewpoint of interface effect and percolation behavior Behavior was analyzed. The results show that the particles / polymer composite particles formed when the grafted nanoparticles are filled into the polymer can play a synergistic effect as a whole, resulting in strong interfacial effects and possibly double percolation behaviors, thereby facilitating the development of nanoparticles Special performance
