Figure 2

(A) Representative plots of ΔD versus time (t) (5th overtone) for XG adsorbed onto RC (⊞ 10 mg·L–1 XG, □ 500 mg·L–1 XG), s-CNC (⋈ 10 mg·L–1 XG, Δ 500 mg·L–1 XG), and d-CNC (○ 10 mg·L–1 XG, ⊗ 500 mg·L–1 XG) films measured in the cellulose-film-thickness-independent regime (dRC = 22 nm, ds-CNC = 26 nm, dd-CNC = 30 nm). (B) ΔD versus concentration for XG adsorbed onto d-CNC films. The zero-point ΔD is provided as a reference (---).
