The present work focuses on surface functionalization, characterization, biodegradability and barrier properties of MOSF as a practicable reinforcement in PVA matrix. Film-forming dispersions at different concentrations of alkali and acid treatments were casted at room temperature. The effect of surface modifications on the developed film’s compositional, physical, mechanical, biodegradability and barrier properties were analyzed. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) were used to describe the functional composition, formation and surface morphology of the film. The 5% acid treated film significantly increases the tensile strength (33.69 MPa) and flexural strength (56.612 MPa), which was close to the frequently used LDPE and HDPE package films. Composite films were moisture absorptive but simultaneously capable to maintain uniformity and composition upon modifications. Lower water vapor permeability (1.42 × 10⁻¹⁰gs⁻¹ m⁻¹ Pa⁻¹), eminent biodegradability proved the suitability of composite film for various packaging applications.

目前的工作集中在MOSF的表面功能化，表征，生物降解性和阻隔性能上，作为PVA基质中的切实可行的增强材料。在室温下流延不同浓度的碱和酸处理的成膜分散体。分析了表面改性对显影膜的成分，物理，机械，生物降解性和阻隔性能的影响。傅里叶变换红外光谱（FTIR），X射线衍射（XRD），扫描电子显微镜（SEM）和原子力显微镜（AFM）用于描述薄膜的功能组成，形成和表面形态。经过5％酸处理的薄膜可显着提高抗张强度（33.69 MPa）和抗弯强度（56.612 MPa），与经常使用的LDPE和HDPE封装薄膜接近。复合膜具有吸湿性，但同时能够在改性后保持均匀性和组成。较低的水蒸气透过率（1.42×10^-10 gs ^-1 m ^-1 Pa ^-1），卓越的生物降解性证明复合膜适用于各种包装应用。
