Polylactic acid(PLA) is a biodegradable polymer with biocompatibility and low toxicity, making it suitable for a wide range of applications such as food packaging and 3D printing filaments. However, PLA exhibits limitations including low thermal stability and insufficient mechanical strength. To address these defects, this study focused on improving the mechanical properties and thermal stability of PLA by grafting with cellulose fibrils. Dialdehyde cellulose(DAC) was synthesized by oxidizing cellulose fibrils with sodium periodate, introducing reactive aldehyde groups to enable grafting with PLA. The DAC was subsequently modified with octadecylamine(ODA), an eco-friendly hydrophobic surface modifier, to promote efficient grafting between ODA-DAC and PLA. This modification facilitated direct grafting of alkyl amine onto the aldehyde groups of DAC through a Schiff base reaction without the use of additional crosslinkers. The resulting ODA-DAC/PLA composite was fabricated via the solvent casting method, and its properties were evaluated to assess its potential for improving the performance of biodegradable plastics.
