This study develops a new type of poly(vinyl alcohol) (PVA) composite film by incorporating hydrophilic fumed silica and microfibrillated cellulose (MFC) as reinforcing agents through low-cost synthesis method. The addition these materials significantly enhanced the film's mechanical properties hydrophobicity. A three-dimensional network structure formed hydrogen bonding interactions between PVA, MFC, led to notable improvements in tensile strength (71.1%) Young's modulus (146%) optimal formulation with 5% MFC 3% silica. Additionally, films exhibited maximum water contact angle 90.3°, indicating significant reduction hydrophilicity development more hydrophobic surface. X-ray diffraction analysis confirmed that incorporation crystallinity PVA films, improving their structural stability. work demonstrates synergistic effect offering promising solution for sustainable packaging improved properties.
