Fig. 2. — (A) 2D WAXS patterns of representative S·DWNT fibers. (B) Equatorial and (C) meridional radial profiles showing the transition from bundles to highly crystalline graphitic domains upon high-temperature annealing. (D) Plot of crystal sizes transversal (L_c) and parallel (L_a) to the fiber axis for CNT fibers as well as conventional graphitic CFs from different precursors (48). (E) Orientation parameters ⟨cos²(ϕ)⟩ calculated from the interlayer reflections (Eq. 1).
