It has been also reported that the layer silicate intercalates can undergo an organic solid-state reaction within the interlayer region, such a reaction can be considered as highly regiospecific due to the distinct surface properties such as surface acidity or layer charge [5-7]. Moreover, size- and shape-selective layer silicates have been prepared [8,9] and the catalytic properties investigated in recent years [10]. 

The XRD patterns for various possible arrangements of layered silicates in biopolymers are shown in Figure 1. For an itmniscible arrangement (microcomposite) of layered clays in a biopolymer matrix, the structure of the layered silicate in the composite is not affected. Thus, XRD pattern for the microcomposite should remain same as that obtained for the pure layered silicate. Intercalation of the polymer...

Toughness reduction was also noticed when layered silicate was incorporated in PS. In the related study PS/layered silicate micro- and nanocomposites were produced. Microcomposite was generated by direct melt blending of PS with the silicate. Intercalated nanocomposites were, however, achieved when the pristine layered silicate was swollen in water before adding the related slurry in...
