摘要: In this study, chitin nanofiber (ChNF) was deacetylated on the crystalline surface by NaOH treatment, leading to fibrillation of mostly individualized nanofibers with high aspect ratio. The small diameter and strength make them promising reinforcing fillers for composites. Herein introducing into gelatin, surface-deacetylated (S-ChNF)/gelatin nanocomposites were fabricated in different component ratios using immersion method followed drying. Due effect attributed S-ChNF, mechanical properties S-ChNF/gelatin significantly improved both stress Young's modulus while still maintaining transparency regardless content. Morphology Fourier-transform infrared characterization revealed that S-ChNF preserved nanonetwork structures gelatin matrix exhibited good compatibility through hydrogen bonding, which further confirmed improvement properties. Therefore, these based biocompatible biodegradable raw materials have potential applications biomedical food packaging industries.
