Characterization of Montmorillonites by Infared and Raman Spectroscopy for Preparation of Polymer-Clay Nanocomposite

Popis výsledku v původním jazyce

The contribution demonstrates the potential and applicabillity of infrared and Raman spectroscopy in identification and structural characterization of montmorillonites. The vibrational spectra of selected montmorillonites, obtained by FT-IR spectroscopy in the near and middle IR region together with FT-Raman spectra are presented.The detailed structural chemistry of clay minerals is an important aspect of polymer-clay nanocomposite research. A variety of analytical methods are currently available for material characterization.nKeep in mind, however, that each method has some limitations. The best results are usuallynachieved by a combination of several analytical methods. The contribution demonstrates the potentialnand applicability of infrared and Raman spectroscopy in identification and structural characterizationnof montmorillonites. The vibrational spectra of montmorillonites (SAz-2, STx-1, SWy-2nand Kunipia-F), obtained by Fourier Transform infrared spectroscopy in the near infrared regionn(8000–4000 cm−1) and in the middle infrared region (4000–400 cm−1) together with Fourier TransformnRaman measurements in the region from 4000–50 cm−1, are presented. The aim of thenexperimental study was to compare the spectral data of both analytical techniques in terms ofntheir sensitivity to chemical composition, isomorphic substitution of central atoms, and layer stackingnorder of the clay minerals. The results confirmed that Fourier Transform infrared spectroscopynthrough middle infrared and near infrared spectral regions provided the most comprehensive informationnabout octahedral, tetrahedral and hydroxyl structure units of montmorillonites.
