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.
