Abstract
In this work, a detailed Raman spectroscopy study of the polymer clay nanocomposite (PNC) prepared by using a polymer blend salt complex has been reported. Raman spectroscopy study reveals a change in peak profile of CH2 and COC bond upon intercalation of polymer chain inside the clay gallery. Further upon PNC formation the local environment of the polymer chain also changes. As a result, a change in the ion dissociation effect has been observed and it has been analyzed by using Raman peak profile of the anion peaks. The free anion area has been calculated and clearly, shows significant changes with clay concentration. This free anion area is directly correlated with conductivity result of the system under study, indicating the change in ion dynamics upon PNC formation.
