Comparisons of the morphologies (AFM images) and height distributions of cellulose fibrils produced from untreated and acid treated bleach Eucalyptus pulp (BEP) fibers under three severities after 60 min milling in a SuperMassColloider.
(a) CHFX = 0 (XR = 1.0), DP = 785 ± 16, scale = 2 μm (untreated BEP); (b) CHFX = 1.21 (XR = 0.72), DP = 638 ± 14, scale = 1 μm; (c) CHFX = 4.62 (XR = 0.50), DP = 485 ± 8, scale = 200 nm; (d) CHFX = 14.90 (XR = 0.31), DP = 286 ± 8, scale = 100 nm.
