Characterizations of prepared CNF/BG hybrids by using SEM observation (A1, B1, C1), element mapping (A2, B2, C2) and EDS analysis (A3, B3, C3): (A1–A3) CNF/BG (49 s); (B1–B3) CNF/BG (68 s); (C1–C3) CNF/BG (86 s).

The insets in SEM images are fiber diameter distribution and TEM image of the corresponding CNF/BG hybrid.
