Abstract The chemistry organobentonites were synthesized by means of the ionexchange reaction between single-octadecyl trimethyl ammonium chloride(SOAC), di-octadecyl dimethyl ammonium chloride (DOAC) , tri-octadecyl methylammonium chloride (TOAC) quaternary ammonium salts and sodium base bentonites, respectively. The authors used FTIR, X-ray diffraction diagram and DSC thermograms to characterate the structure of the modified bentonites, and discussed the effect of different quaternary ammonium salt on the properties of organobentonites. The results showed that ion of the surfactants had entered into the chip layer of the bentonites, and changed the hydrophilic environment of the chip layer into hydrophobic environment and increased the distance among the chip layer, all of these had laid a base for the preparation of the nanometer composite material of high polymer/bentonite.
