Clay Minerals and Polymers : From Soils to Nanocomposites(Clay-Polymer)

概要

The interactions of clay minerals with humic substances and synthetic organic polymers have been investigated for more than five decades. More recently, the focus of attention has shifted to the synthesis and development of clay-polymer 'nanocomposites'. Since the nanometer-thick silicate layers are more or less uniformly dispersed in the polymer matrix, these novel hybrid materials display superior mechanical, optical, thermal, and gas barrier properties. Here we outline the principles and practice of the clay-humic and clay-polymer interaction, with particular reference to work done in our laboratory. Because of space limitations only the important findings and conclusions will be presented. As far as is possible, we will also refer to key papers and reviews, rather than cite individual authors.
