(a, b) Schematic illustrations demonstrating the role that GO has in providing additional bonding sites (dashed boxes) between the NFC chains. (c–d) Molecular dynamics models for NFC chains with and without GO sheets. The insets show typical equilibrium structural configurations from different perspectives before the right NFC chains slide out. (e) Comparison of the sliding force as a function of sliding displacement between the above two cases (i.e., with and without GO sheets). GO, graphene oxide; NFC, nanofibrillated cellulose.
