Abstract

Clay montmorillonite K10  was organically modified by cation exchange reaction with methyl orange.  The clay modified by methyl orange (K10DC) was characterized by infrared spectroscopy, X-ray diffraction, thermogravimetric analysis and scanning electronic microscopy. The epoxy coatings containing 2% clay K10DC was prepared and the dispersion degree of clay in coating was evaluated. Structure analysis by infrared spectroscopy  indicated that vibration bands at 1601 cm-1 and 1389 cm-1 characteristic of C-H bond in aromatic ring and C-N bond of methyl orange were also found in the spectra of clay K10DC. XRD analyze showed that the d001 spacing of clay-K10DC was 16.1 Å. These results indicate the intercalation of methyl orange molecules between silicate layers. Thermogravimetric analyze showed that the organic content in clay K10DC was 25,3 %. SEM observation demonstrated that in clay K10DC the silicate platelets are better separated then in pristine clay. XRD analyze results indicated that epoxy coating containing 2 % clay K10DC was intercalated nanocomposite.
