      abstract     = {The complex architecture of wood motivates studies of
                      bioinspired materials that combine strength, toughness, and
                      mechanical integrity. We explore the interplay between
                      nanofiber alignment and molecular interactions in composite
                      filaments formed from cellulose nanofibers (CNFs) and a
                      dendritic polyampholyte, Helux. Helux enhances strength by
                      $60\%$ and increases toughness 5-fold through ionic bonding
                      and thermal covalent cross-linking. However, wide-angle
                      X-ray scattering (WAXS) reveals reduced nanofiber alignment
                      in Helux-containing samples, resulting in a $25\%$ decrease
                      in stiffness─highlighting a trade-off between structural
                      order and cohesion. Polarized optical microscopy (POM) and
                      in situ small-angle X-ray scattering (SAXS) attribute this
                      reduced alignment to enhanced rotary diffusion, driven by
                      carboxylate groups of the Helux. With Helux, multivalent
                      links across the nanofibers give a denser and tougher
                      network with fewer voids. This behavior resembles lignin and
                      hemicellulose interactions in wood, where flexibility and
                      cohesion govern the performance.},
