An Easy Preparation of Hybrid SiO₂@Poly Acrylic Acid Nanoparticles

Abstract:

Nanometer materials are widely used in the modification of polymer materials such as polypropylene because of its unique performance. nanocomposite material,which expended the application field of polymer ,is a kind of new composite materials with high performance ratio and widely application prospect .This paper adopted the surface-initiated technology to coat and modify the surface of nanosilica,which solved the problem of the agglomeration and interface compatibility of the nanometer particles and improved its dispersion in the acrylic acid,then prepared SiO₂/PAA nanocomposite .The composite was characterized by infrared spectrum and transmission electron microscopy (TEM) ,etc.The research results showed that the nanocomposite prepared by in-situ polymerization technology had higher toughness ,strength and more excellent comprehensive performance.
