Figure 6

Paired comparisons of the morphologies (AFM images) and height distributions of cellulose fibrils with similar DP but produced under different hydrolysis severities and SMC milling durations.

(a1) scale = 2 μm and (a2): DP = 772 ± 9, CHFX = 1.21 (XR = 0.72), milling tm = 30 min, paired with Fig. 2a1,2a2; (b1) scale = 1 μm and (b2): DP = 543 ± 14, CHFX = 14.90 (XR = 0.31), milling tm = 15 min, paired with (b3) scale = 1 μm and (b4): DP = 544 ± 14, CHFX = 4.62 (XR = 0.50), milling tm = 45 min; (c1) scale = 200 nm and (c2): DP = 450 ± 14, CHFX = 14.90 (XR = 0.31), milling tm = 30 min, paired with Fig. 2c1,2c2.
