Abstract
This research study the formulation and properties of all cellulose composite (acc) films isolated from oil palm empty fruit bunch (opefb) using 8% lithium chloride/n-n dimethylacetamide (licl/dmac) solvent and a surface-selective dissolution technique. Opefb is an abundant yet underutilized renewable resource in malaysia. In response to the growing demand for sustainable, high-performance materials, this study investigates into the impact of process condition parameters on the tensile, structural, thermal, and water interaction characteristics of acc films. The fabrication of acc involved utilizing process condition parameters formulations with dissolution times of 5, 15, 30, and 45 minutes, combined with initial cellulose concentrations of 1%, 3%, and 5%. A straightforward pulping, bleaching, and solution casting technique were employed to extract opefb cellulose pulp, ensuring efficient film fabrication. Tensile analysis reveals that the best combination of 3% initial cellulose concentration and 15 minutes dissolution time results in acc films with superlative tensile strength (44.41 mpa) and young’s modulus (3.26 gpa). X-ray diffraction (xrd) studies reveal a structural transition of the dissolved cellulose from cellulose i to cellulose ii, while also confirming the coexistence of both cellulose i and ii phases., leading to a notable decrease in the degree of crystallinity observed in acc films.
