Abstract

A method for making a nanocomposite material includes introducing a solution including a nanofiller material and a supercritical fluid into a molten polymeric material within an extruder. The supercritical fluid is caused to substantially instantaneously convert to a gas phase, thereby forming the nanocomposite material having the nanofiller material substantially homogeneously dispersed therein.
