Abstract
Nanocomposites may be produced by mixing dispersions of polymers and dispersions of clay minerals. After mixing, the dispersions may be destabilized with the addition of appropriate compounds. The flocculated solid material exhibits characteristics of a nanocomposite, such as exfoliation of the clay mineral platelets as indicated by x-ray diffraction analysis.
