Montmorillonite (Na-MMT or Mont-0) is easily dispersed at room temperature in a suitable amount of distilled water due to its high hydrophilicity [11, 12], The aqueous solution is containing a calculated amount of the cationic surfactant (CTAB) which can cause the desired level of organophilicity after cation exchange with the montmorillonite's sodium.

To improve the interaction, the charge balancing interlayer cations (typically sodium) present on the MMT are most often replaced by alkyl ammonium ions, facilitating the organophilicity of the layered silicate surface [4-6].

Although the organophilicity of the clay is enhanced by a higher interlayer population density, the PET chains would penetrate with difficulty the galleries because of saturation by surfactant molecules or high organic content.

In the preparation of exfoliated PS/LDH composites, it is important to increase the organophilicity of the originally hydrophilic LDH, to ensure the promoted swelling of the double layered aluminate structure by styrene monomer.

Thus, the incorporation of amine governs the organophilicity of the clay.

A short review on rubber/clay nanocomposites with emphasis on mechanical properties

By judicious selection of the organic cations, the nature of silicate interlayer, however, can be controlled and thus polymers with varying degrees of polarity and organophilicity intercalated into the galleries.

Since the natural clay is highly hydrophilic, it is important to improve its organophilicity so that it will be compatible with organic polymers.
