    • note
    • Durin the process of intercalation, the polymer chains penetrating the clay layers have to overcome a large entropy barrier, which is due to the closely packed clay layers. The entropy barrier can be lowered by favorable enthalpic contributions that are possible by modification of the clay with a suitable organic moiety so that the polymer-clay interactions are more favorable than the clay-surfactant interactions. Increasing the modifier concentration of the surfactant leads to more efficient packing and increased interlayer contact between the clay layers, and this results in more cohesive van der Waals interactions between the clay layers and, therefore, a greater interlayer solidlike character.
