The outstanding properties of polymer-clay nanocomposites are achieved at a much lower volume fraction, compared with conventional composites. Polymer-clay nanocomposites can be processed using common techniques, such as extrusion and casting, which are superior to the cumbersome techniques used for the conventional composites.

文摘Because of the dispersion at the nanometer level, polymer-clay nanocomposites exhibit superior properties in comparison with pure polymer or conventional composites; this includes properties such as barrier properties , improved thermal stability and flame retardancy. The outstanding properties of polymer-clay nanocomposites are achieved at a much lower volume fraction, compared with conventional composites.

Hence, polymer-clay nanocomposites have important potential commercial value.
