Preparation of nanocellulose from bagasse and its application in chitosan composite films

< 0.05). The morphology of CNC and CNC/CS composite films was observed by scanning electron microscopy. The structure was characterized by Fourier transform infrared spectroscopy and X-ray diffraction, and thermal stability was analysed by thermogravimetric analysis. Hydrogen bonding between nanocellulose and CS enhanced the cohesion of the composite film. The newly prepared CNC/CS composite film showed good mechanical properties, barrier properties and stability. It has potential applications in the food packaging industry to extend the shelf life of food and is energy-saving and environmentally friendly.
