The transmission electron micrographs of the unmodified and
organo-modified kaolins were obtained using a 300 kV HRTEM of FEI
(model — Tecnai 30 G2, S-Twin). Transmission electron microscopic
analysis of samples was done using FEI, Netherlands, Tecnai T30 with
EDAX system. The sample was dispersed in acetone by sonication for
30 min and drop-casted on copper grid. Themorphology and particle dimensions
were analyzed by TEM under 300 kV.
