Abstract
A method for forming a nanocomposite material includes introducing a nanofiller material having polar end groups into an extruder having a polymeric material therein. An unsaturated shielding material is introduced into the extruder. The unsaturated shielding material reacts with the polar end groups, thereby forming a shielded nanofiller material. The shielded nanofiller material is grafted to the polymeric material, thereby forming the nanocomposite material. The nanofiller material therein is substantially exfoliated, and the nanocomposite material exhibits enhanced physical properties.
