The crystallinity of the samples containing SSGO was higher than that of BC0. The higher crystallinity of the BC1, BC2, and BC3 likely improved their tensile properties. These results showed that the presence of SSGO in the media favored the crystallization process and reduced the relative amorphous region of the BC. The appearance of various peaks at the same position indicates that SSGO present in the media does not disturb the basic crystalline arrangements of BC. However, the crystal size was disturbed to some extent (Table 1).
