Investigation on Intercalation Modification of Sodium-montmorillonite by Cationic Surfactant

doi:10.3724/SP.J.1077.2011.12049

Abstract

Abstract: Sodium-montmorillonite (Na⁺-MMT) was intercalation modified with octadecyl trimethyl ammonium chloride (OTAC) in aqueous suspension via an ion exchange mechanism. Fourier transform infrared spectroscopy (FTIR) study indicates that OTAC is successfully intercalated into Na⁺-MMT layers and/or adsorbed on the surface of Na⁺-MMT. X-ray diffraction (XRD) analysis revealed that the interlayer spacing of the Na⁺-MMT was extended with the content of OTAC increasing, and the maximum spacing can reach about 3.80 nm. Results of scanning electron microscopy (SEM) analysis reveals the morphologies change from soherical-like particles to high-aspect ratio flakes after modification. Different configurations of OTA⁺ chains within MMT interlayer are proposed based on the above analysis. The results of contact angle and the dispersion analysis show that the surface wettability of Na⁺-MMT is converted from hydrophilic to organophilic.
