For the first time, we investigate the synergistic effect of one-dimensional nanofibrillated cellulose (NFC) and two-dimensional graphene oxide (GO) to facilitate low-cost, mechanically strong hybrid microfibers. Both experimental and molecular dynamics simulations were carried out. Such GO-NFC hybrid microfibers show an elastic modulus of 34.1 GPa, an ultimate tensile strength of 442.4 MPa and a toughness of 4.9 MJ m−3, which outperform among the best GO fibers in literature. This study promotes a new design strategy to create high-performance microfibers for a range of applications.
