3.3 Characterization of SCG/PP composites
3.3.1 Dispersion of SCG in PP matrix and Mechanical properties
The dispersion of SCG, NSCG, and ASCG in PP was observed by microscope
and the mechanical properties of the samples are shown in Figure 5. As
can be seen from the picture, SCG (a) has a large agglomeration and
uneven distribution in PP, and the dispersion of NSCG (b) has not been
significantly improved. However, ASCG (c) aggregates in PP became
smaller and dispersed evenly. Combined with the character analysis of
SCG, this observation can be attributed to the fact that the residual
oil content of SCG and NSCG is greater than that of ASCG. The presence
of oil causes agglomeration and affects the dispersity of SCG.
