Cellulose Nanoparticles Prepared by Ionic Liquid-Assisted Method Improve the Properties of Bionanocomposite Films

Bionanocomposites have garnered wide interest from the packaging industry as a biocompatible alternative to non-biodegradable petroleum-based synthetic materials. This study presents simple and eco-friendly produce cellulose nanoparticles using protic ionic liquid, effects of their incorporation in cassava starch chitosan films are evaluated. Bionanocomposite prepared solvent casting method characterized X-ray diffraction, Fourier transform infrared spectroscopy, zeta potential, thermogravimetric analysis, transmission electron microscopy. The achieved yield is 27.82%, crystalline index 67.66%. nanoparticles’ (concentration 0.1 0.3% wt) results progressive reduction water vapor permeability up 49.50% 26.97% for bionanocomposite films, respectively. with 0.1% exhibit significantly increased flexibility compared those without any addition. increases thermal stability affecting mechanical properties. obtained an pathway avoiding classic acid hydrolysis can be simple, sustainable, viable bionanocomposites tailored properties, useful applications industry.
