Abstract :A new surface modification for sodium bentonite clay insert ignore into journalissuearticles values(Na-Bent); was analyzed and the organo-modified bentonite clays were obtained with the sequential mixture of cationic surfactants; these were namely long chained insert ignore into journalissuearticles values(cethyltrimethylammonium bromide-CTAB);, short chained insert ignore into journalissuearticles values(tetraethylammonium bromide-TEAB); and ringed insert ignore into journalissuearticles values(benzyltriethylammonium bromide-BTEAB); surfactants. These modified organoclays were characterised by X-ray diffraction insert ignore into journalissuearticles values(XRD);, Fourier transform infrared insert ignore into journalissuearticles values(FTIR); spectrometry, Scanning Electron Microscopy insert ignore into journalissuearticles values(SEM); and zeta potential analysis. It was seen that the highest basal spacing of the organoclay was obtained by insert ignore into journalissuearticles values(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.
