摘要: In the present study, graphene-based nanocomposites containing different amounts of nanofiller dispersed into Bis-GMA/tetraethyleneglycol diacrylate (Bis-GMA/TEGDA) polymer matrix have been prepared. particular, graphene dispersions, produced at high concentration (up to 6 mg/ml) by simple sonication graphite in TEGDA monomer, used for direct preparation nanocomposite copolymers with Bis-GMA. The morphology obtained has investigated as well their thermal and mechanical properties. SEM analyses clearly shown that deeply interacts matrix, thus resulting a reinforcing effect on material proved compression hardness tests; variance, does not seem affect glass transition temperature networks.
