Synthesıs And Characterızatıon Of Poly(Vınıly Chlorıde)/Bentonıte Nanocomposıtes
In this study, PVC / bentonite nanocomposite has been prepared by melt blending. Bentonite was modified first with cethylbromide before it was used in nanocomposite.
Thermal properties of PVC / bentonite nanocomposites characterized by Differential Scanning Calorimetry ( DSC ) and temogravimetric analysis (TGA). DSC analysis showed that Tg’ s were observed in all compositions.
By analyzing each sample of DSC, it was found that the Tg of nanocomposite was higher than the Tg of pure PVC, but not by much.
Structural characterization of the nanocomposites has been investigated by using SEM ( Scanning Electron Microscope).
From a structural analysis it was observed that the interaction of bentonite with polymer was different than that of the polymer - polymer interaction.
