摘要

The present work describes the exfoliation of clay through crosslinking with 3- (acrylamidopropyl)trimethylammonium chlorideo- acrylamide (APTAC/AM) which made the polymer end-tethered onNa-MMT. However, the way in which APTAC/AM interacts with the surface of MMT has not yetbeen studied. APTAC/AM widened the gap between clay layers and facilitates comonomers penetrateinto clay. The exfoliated structure of extracted nanocomposite was confirmed by Fourier transforminfrared (FTIR), X-ray powder diffraction XRD, thermogravimetric analyses (TGA) and transmissionelectron microscopy (TEM). Results of FT-IR, TGA and XRD analyses showed that APTAC/AMinteracted with clay, but to various extents. The inhibition effect of APTAC/AM-MMT on thecorrosion of steel in 1.0 M HCl solution was studied by potentiodynamic polarization curves andelectrochemical impedance spectroscopy (EIS) methods. All electrochemical measurements indicatethat APTAC/AM-MMT functioned as a good inhibitor in 1M hydrochloric solution and inhibitionefficiency increased with APTAC/AM-MMT concentration. Polarization curves indicate thatAPTAC/AM-MMT acts as mixed-type inhibitor. EIS spectra exhibit one capacitive loop. The chargetransfer resistance (Rct) increases with APTAC/AM-MMT concentration, while double layercapacitance (Cdl) decreases.
