Bio-based nanocomposite films were successfully developed using nanofibrillated cellulose (NFC) as the reinforcing phase and kappa-carrageenan (KCRG) as the matrix. NFC was successfully synthesis from short stable cotton fibers by chemo-mechanical process. The bionanocomposites were prepared by incorporating 0.1, 0.2, 0.3, 0.4, 0.5, and 1wt% of the NFC into a KCRG matrix using a solution casting method there characterization was done in terms of thermal properties (DSC), morphology (SEM), water vapor transmission rate (WVTR), oxygen transmission rate (OTR), X-ray diffractograms (XRD), and tensile properties. The main conclusion arising from the analysis of the result is that the bionanocomposites containing 0.4wt% of NFC exhibited the highest enhancement in tensile strength it is almost 44% improvement. WVTR and OTR results showed improvement of all nanocomposite film compare to control KCRG film.
采用纳米原纤化纤维素（NFC）作为增强相和角叉菜胶（KCRG）作为基质，成功制备了生物基纳米复合材料薄膜。NFC 是通过化学机械法从短稳棉花纤维中成功合成的。通过溶液浇铸法将 0.1、0.2、0.3、0.4、0.5 和 1wt%的 NFC 掺入 KCRG 基质中，制备了生物纳米复合材料，并对其进行了热性能（DSC）、形貌（SEM）、水蒸气透过率（WVTR）、氧气透过率（OTR）、X 射线衍射图（XRD）和拉伸性能的分析。从结果分析中得出的主要结论是，含有 0.4wt%NFC 的生物纳米复合材料表现出最高的拉伸强度增强，几乎提高了 44%。WVTR 和 OTR 结果表明，与对照 KCRG 薄膜相比，所有纳米复合材料薄膜的性能都得到了改善。
