چکیده انگلیسی
Poly(butylene succinate-co-adipate) (PBSA)/layered silicate nanocomposites were prepared by melt extrusion of PBSA and three different types of commercially available organically modified montmorillonite (OMMT). Using three types of OMMT modified with three different kinds of surfactants, the effect of organic modification on nanocomposites was investigated by focusing of three major aspects: morphological study, property measurements, and melt rheological behavior under both small and large deformation flows. X-ray diffraction (XRD) patterns revealed that increasing the level of interactions (miscibility) between the organic modifier and PBSA matrix increases the tendency of the silicate layers to delaminate and distributed nicely within the PBSA matrix. Transmission electron micrographic (TEM) observations showed that the ordering of silicate layers in PBSA matrix is well matched with the XRD patterns. Thermal analysis revealed that extent of crystallinity of PBSA matrix is directly related to the extent of exfoliation of silicate layers in the nanocomposites. Dynamic mechanical analysis and tensile property measurements showed concurrent improvement in mechanical properties when compared to the neat PBSA and the extent of improvement is directly related to the extent of delamination of silicate layers in the PBSA matrix. The same tendency was also observed in melt rheological measurements.
