摘要

本研究采用NaOH/尿素/水为溶剂，采用相转化技术，以榕树树皮布纤维为原料制备了纤维素薄膜。以7重量%和8重量%的微晶纤维素（MCC）的浓度形成膜，所述微晶纤维素是从榕树树皮布纤维中分离的。用扫描电子显微镜（SEM）、傅立叶变换红外光谱（FTIR）、x射线衍射（XRD）、热重分析（TGA）和微控电子万能试验机对其形态、理化和力学性能进行了检测。所得再生纤维素（RC）膜表面形貌粗糙，拉伸强度良好（19.85±0.13MPa），具有相当大的应变塑性行为。然而，它们在高达280°C的高温下是热稳定的。本研究中的纤维素薄膜有可能作为可生物降解的包装材料，以扩大榕树皮的应用范围

PREPARATION AND CHARACTERIZATION OF CELLULOSE FILMS FROM FICUS NATALENSIS BARK CLOTH FIBERS

In this study, cellulose films were prepared from Ficus natalensis bark cloth fibers via phase inversion technique using NaOH/urea/water as the solvent. Films were formed at a concentration of 7 wt. % and 8 wt. % of microcrystalline cellulose (MCC) as isolated from Ficus natalensis bark cloth fibers. Their morphology, physiochemical, and mechanical properties were examined with scanning electron microscopy (SEM), Fourier transform IR spectroscopy (FTIR), x-ray diffraction (XRD), thermal gravimetric analysis (TGA) and microcontrolled electronic universal testing machine. The resultant regenerated cellulose (RC) films exhibited rough surfaces morphologically, good tensile strength (19.85 ± 0.13 MPa), exhibited a plastic behavior with considerable strains. However, they are thermally stable at higher temperatures up to 280 °C. Cellulose films from this study could potentially act as biodegradable packaging materials to upgrade the scope of application of Ficus natalensis bark
