Given the widespread prevalence of viruses, there is an escalating demand for antimicrobial composites. Although composite dialdehyde cellulose and silver nanoparticles (DAC@Ag1) exhibits excellent antibacterial properties, its weak mechanical characteristics hinder practical applicability. To address this limitation, nanofibers (CNFs) were initially ammoniated to yield N-CNF, which was subsequently incorporated into DAC@Ag1 as enhancer, forming DAC@Ag1/N-CNF. We systematically investigated optimal amount N-CNF characterized DAC@Ag1/N-CNF using FT-IR, XPS, XRD analyses evaluate additional properties. Notably, mass ratio found be 5:5, resulting in a substantial enhancement with 139.8% increase tensile elongation 33.1% strength, reaching 10% 125.24 MPa, respectively, compared alone. Furthermore, inhibition zones against Escherichia coli Staphylococcus aureus significantly expanded 7.9 mm 15.9 mm, surpassing those alone by 154.8% 467.9%, indicating remarkable improvements efficacy. Mechanism analysis highlighted synergistic effects from chemical covalent bonding hydrogen DAC@Ag1/N-CNF, enhancing properties significantly. The addition markedly augmented film, thereby facilitating broader application field.
