Fig. 4 represents the SEM images of the rubber composites.
It can be seen from the images that EG flakes were
randomly distributed in the different rubber matrix and the lateral
size of the EG was exposed for the loaded rubber composites prepared
by melt blending, which indicated moderate interfacial
bonding between EG and the rubber matrices. But for the i-MG
loaded rubber composites, the microstructure of the fractured surfaces
displayed the close contact and high embedding of i-MG
flakes with rubber matrices, indicating a good interracial interaction
between i-MG and the rubber matrices. SEM images of the
EG and i-MG filled rubber compounds showed rough, tortuous
fractured surface and broad tear paths. It can be suggested that
EG and i-MG sheets were dispersed in the rubber matrix in the
presence of CB and changed the crack
