Notas: Low-field NMR, polycarbonate, nanocomposite
The nanocomposites based on polycarbonate and organophilic montmorillonite were prepared by solvent cast method, using different ratios of organophilic montmorillonite. The intermolecular interactions and molecular dynamics of the nanocomposites obtained have been evaluated by spin-lattice relaxation time determined by nuclear magnetic resonance. They have also been characterized by X-ray diffraction to confirm the changes in the organoclay structure after being incorporated in the polymeric matrix. The thermal stability of both polymer and nanocomposites were also studied by thermogravimetric analysis. The glass transition temperature was determined by differential scanning calorimetry. The sum of all results indicates that nanocomposites obtained presented a predominant intercalated morphology.
