Abstract
A new surface modification for sodium bentonite clay (Na-Bent) was analyzed and the organo-modified bentonite clays were obtained with the sequential mixture of cationic surfactants; these were namely long chained (cethyltrimethylammonium bromide-CTAB), short chained (tetraethylammonium bromide-TEAB) and ringed (benzyltriethylammonium bromide-BTEAB) surfactants. These modified organoclays were characterised by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectrometry, Scanning Electron Microscopy (SEM) and zeta potential analysis. It was seen that the highest basal spacing of the organoclay was obtained by (CTAB+BTEAB) surfactants. The synergistic effect of the surfactants on the interlayer space of the organoclay in terms of developing novel clay based nanocomposites was investigated.
