N2 - We report herein a flexible, light and electrically conductive composite film based on polyvinyl alcohol (PVA) matrices. Cellulose nanofibers (CNFs) were used as reinforcement to improve the mechanical properties of the PVA. Addition of silver nanowires (AgNWs) was crucial in enhancing the thermal stability and conductivity of the resulting PVA/CNF-AgNWs composite. The CNFs were obtained through a mechanical defibrillation process and the AgNWs were synthesized via a solvothermal method. A simple casting method combined with a drop cast process was chosen for producing AgNW film on the surface of the composite. The PVA/CNF-AgNWs composite film obtained was superior to the PVA/CNF composite film in terms of thermal stability, tensile strength (up to 38.12 ± 0.53 N/mm 2) and conductivity (8.92 × 10−2 vs 9.46 × 10−12 S/m). These results highlight the potential application of the PVA/CNF-AgNWs composite as a candidate film for the production of flexible electronics.
