| In this thesis, montmorillonite were modified and PS/MMT nanocomposites were prepared by intercalation polymerization melt blend and in situ polymerization respectively. The structure and physical properties were studied by FT-IR, XRD, TEM, DDA, TG. The results indicated that Sodium laurylsulfonate has excellent intercalation effect on Montmorillonite. The materials obtained through three different methods are all nanocomposites, possessing changed structure and properties with different contents of Montmorillonite. Compared with pure PS, the nanocomposites possessed desired property, such as increased thermal stability and impulsion intensity. |
