摘要
A comparative study of nano-SiO2/PP composites prepared by reactive compatibilization was conducted. Nano-SiO2 was first grafted with three polymers bearing specific reactive groups. The grafted particles were then melt-compounded with functionalized and matrix PP. Due to the reaction between the grafted polymers and functionalized PP, nano-SiO2 was covalently connected to the matrix and the mechanical properties of the nanocomposites were significantly improved. It was found that chain flexibility of the graft polymers is critical for inducing plastic deformation of the matrix, provided that interfacial chemical bonding has been built up.
