Abstract. This study reports the fabrication and characterization of electrospun poly(vinyl alcohol) /carboxymethyl cellulose (PVA/CMC) nanofibrous films at blend ratios of 10:0, 9:1, 8:2, and 7:3 as a renewable and biodegradable alternative to synthetic polymers. CMC incorporation produced thinner fibres, disrupted PVA crystallinity, and improved thermal stability, increasing degradation onset from ~210 °C to ~225 °C. Mechanical testing showed enhanced reinforcement, with tensile strength increasing from ~0.43 to ~0.57 MPa and reduced flexibility. Higher CMC content increased moisture permeability and UV shielding, with water vapour permeability rising from ~5.2 to ~13.6 × 10⁻¹⁰ g m⁻¹ s⁻¹ Pa⁻¹ and opacity from ~0.6 to ~7.5. Among all formulations, the 8:2 blend offered the best balance of morphology, strength, and barrier properties. These findings demonstrate that tuning the PVA/CMC ratio provides a versatile strategy for designing sustainable nanofibrous films with potential applications in food packaging, biomedical materials, and other eco-friendly products, supporting the transition toward greener material solutions and reducing reliance on single-use plastics.
