Abstract
Methods for synthesizing a polymer functionalized nanoparticle are provided. The method can include attaching a polymeric chain to a nanoparticle, wherein the polymeric chain comprises a plurality monomers, wherein the plurality of monomers comprise alkyl (meth)acrylate monomers. Polymer functionalized nanoparticles are also provided that comprise a nanoparticle defining a surface, and a polymeric chain covalently bonded to the surface of the nanoparticle, wherein the polymeric chain comprises a poly alkyl (meth)acrylate. Nanocomposites are also provided that include a plurality of these polymer functionalized nanoparticles dispersed within a polymeric matrix (e.g., a polyolefin matrix).
