Polymer nanocomposites with layered silicates

Abstract

The topics of current research in the field of polymer nanocomposites with layered silicates are addressed. The factors influencing the efficiency of the clay exfoliation in a polymer during melt processing are summarized, namely type of a machine used, mixing conditions and molecular characteristics of polymers utilized, including that of polymeric compatibilizers. New methods leading to the clay exfoliation in a polymer matrix are described. Application of exfoliation promoter allows to eliminate the necessity to compatibilize organo-modified clay with hydrophobic polymer matrix. Shear induced crystallization of polyolefin based nanocomposites is also addressed; even weak shearing induces alignment of clay platelets, results in polymer chains orientation and enhances the nucleation of crystallization.
