Sugar palm fibre (SPF) was treated with NaClO₂, bleached with NaOH and subsequently hydrolyzed with acid to obtain sugar palm nanocrystalline cellulose (SPNCCs). Bionanocomposites in the form of films were prepared by mixing sugar palm starch (SPS) and sorbitol/glycerol with different nanofiller SPNCCs compositions (0-1.0 wt %) using solution casting method. The resulting fibres and nanocomposites were characterized in terms of morphology (FESEM and TEM), footprint, crystallinity (XRD), light transmittance, biodegradability, physical, water barrier, thermal (TGA, DSC and DMA) and mechanical properties. The length (L), diameter (D) and L/D values of the SPNCCs were 130 ± 30.23, 8.5 ± 1.82 nm, and 15.3, respectively. The SPS/SPNCCs nanocomposite films exhibited higher crystallinity, tensile strength, Young’s modulus, thermal and water-resistance compared to the neat SPS film. The results showed that the tensile strength and moduli of the bionanocomposites increased after being reinforced with SPNCCs and the optimum nanofiller content was 0.5%.

用NaClO ₂处理糖棕纤维（SPF）将其用NaOH漂白，然后用酸水解以获得糖棕纳米晶纤维素（SPNCC）。通过使用溶液流延法将糖棕榈淀粉（SPS）和山梨糖醇/甘油与不同的纳米填料SPNCCs组成（0-1.0 wt％）混合来制备薄膜形式的Bionanocomposites。根据形态（FESEM和TEM），覆盖区，结晶度（XRD），透光率，生物降解性，物理，阻水性，热（TGA，DSC和DMA）和机械性能对所得的纤维和纳米复合材料进行表征。SPNCC的长度（L），直径（D）和L / D值分别为130±30.23、8.5±1.82 nm和15.3。与纯SPS膜相比，SPS / SPNCCs纳米复合膜具有更高的结晶度，拉伸强度，杨氏模量，耐热性和耐水性。
