A Schematic depicting the 3D hierarchical structure of CFNs and the two-step nanofibrillation process. B Illustration of collagen fibril aggregation driven by hydrogen bonding. C Schematic of PSG copolymer introduction to enhance water adsorption, promoting hydration-assisted fibril dispersion. D Schematic of Zr-based coordination to passivate active sites and stabilize the nanofibrillated CFNs. E Photograph of a large-area Nano-CFN membrane. F Cross-sectional and G top-surface SEM images comparing CFN and Nano-CFN samples. Experiments were repeated three times with similar results. H Statistical analysis of fiber diameters before and after nanofibrillation.
