Synthetic adhesives commonly used in shipbuilding, plumbing, and various industrial household applications pose environmental health concerns due to chemical leaching other issues. In this work, we present a sustainable alternative using chitin nanofibers (ChNF) enhance the networking surface binding of biomolecules. We investigate aqueous-based formulations composed tannic acid (TA), poly(vinyl alcohol) (PVA), nanofibers, which form robust adhesive complexes. These are driven by multiple interactions involving phenolic hydroxyl groups, at high densities contribute exceptional adhesion upon drying. Unlike most two-component structural adhesives, ChNF-based introduced here do not rely on organic solvents demonstrate versatility across surfaces with contrasting topologies energies, including stainless steel, polypropylene, wood, others. With an ultimate shear strength reaching up 20 MPa, these rival commercially available for bonding metals, glass. The addition enhances 400%, depending PVA-to-TA ratio. Furthermore, exhibit long-term integrity under wet conditions, showing no signs swelling or degradation. To elucidate mechanisms underlying both dry states, conducted comprehensive analyses, morphological, mechanical, rheological, spectroscopic, thermal, characterizations. findings highlight potential as viable diverse applications.
