ABSTRACT:
A method for modifying a high-density polyethylene (HDPE)-clay nanocomposite is disclosed. The method comprises shearing a melt of the nanocomposite at an effective shear rate. The modified nanocomposite shows significantly increased complex melt viscosity, storage modulus, and loss modulus.
