FESEM characterization of dispersed pre- and post-incinerated nanoclays in saline vehicle. (a) Single (white arrow) and stacked platelets of pristine CloisNa and (b) organomodified Clois30B exhibited stacked or exfoliated platelet morphology with occasional detection of colloidal aluminum silicate agglomerates (black arrow). Inset shows exfoliated platelet with 250 nm scale bar. (c) I-CloisNa possessed a large, amorphous particle structure, while (d) I-Clois30B exhibited either a smooth or pocketed structure. (e) Aluminum silicate colloids were observed in all samples. (f) Heat-inactivated crystalline silica.
