Assembly of nanostructured CNF fibers. Upper image: schematic of double flow-focusing channel used for CNF assembly; the CNF suspension is injected in the core flow (light brown color), deionized water (blue color) in the first sheath, and acid at low pH (light green color) in the second sheath flows; arrows show the flow direction; hydrodynamic and electrostatic interactions at different positions along the channel are illustrated schematically on the right. Bottom images: SEM image (left) of the fiber surface, where the dense fibrillar network with well-preserved anisotropic arrangement can be seen; SEM image (right) of the cross section of the fiber, showing the aligned nanofibrils. Scale bars are 3 μm; in insets are 400 nm. Image credit: Mittal et al, doi: 10.1021/acsnano.8b01084.
