Abstract:
1. An article comprising a polymer-organoclay composite prepared by a method comprising: combining a solvent and an unexfoliated organoclay to form a first mixture, wherein the organoclay comprises alternating inorganic silicate layers and organic layers, and has an initial spacing between the silicate layers, and further wherein the organoclay comprises a quaternary phosphonium or pyridinum cation of formula (2), formula (3), formula (4) or formula (5): wherein Ar wherein Ar wherein Ar wherein Ar exposing the first mixture to an energized condition of a sufficient intensity and duration to increase the initial spacing of the inorganic silicate layers, to form a second mixture; contacting the first or second mixture with a polymer precursor; polymerizing the polymer precursor to form a polymer; and removing at least a portion of the solvent from the second mixture, wherein the inorganic silicate layers remain separated by the polymer after removal of the solvent.
