Raman microspectroscopy as a useful tool for the polymer/clay nanocomposites characterization

Popis výsledku v původním jazyce

During the last decade, interest in polymer/clay composites increased, mostly due to their very good physical, chemical, and mechanical properties, which can be significantly enhanced in various ways compared to conventional polymers. One of the most studied conducting polymers is polyaniline (PANI) which has unique electrical and optical properties, and, in addition, its interaction with clay structure leads to improvement of resulting electrical conductivity. In this study, the clay mineral montmorillonite (MMT) was used. Raman spectroscopy is nondestructive technique and coupled with an optical microscope has a potential for determination of the chemical composition and possible inhomogeneity of the sample. Moreover, Raman spectroscopy is very sensitive to changes in the structure of polymers in terms of its protonation state. Aim of the study was the characterization of PANI/MMT nanocomposites prepared in three different forms (powders, layers, and tablets) by Raman microspectroscopy. In addition, the prepared samples were afterwards calcined to the 1300 oC, where the transformation of PANI to the few-layer graphene was observed. Above that, Raman microspectroscopy was used to creation of the Raman spectral maps which reveal the distribution of the formed few-layer graphene.
