摘要: Crystallized nanocellulose (CNC) was separated from paper-mulberry (Broussonetia kazinoki Siebold) bast pulp by sulfuric acid hydrolysis method and they were blended with agar to prepare bionanocomposite films. The effect of CNC content (1, 3, 5 10 wt% based on agar) the mechanical, water vapor permeability (WVP), thermal properties nanocomposites studied. Changes cellulose fibers in structure, morphology, crystallinity, films evaluated using FT-IR, TEM, SEM, XRD, TGA analysis methods. composed fibrous spherical or elliptic granules nano-cellulose sizes 50-60 nm. Properties film such as mechanical barrier improved significantly (p<0.05) blending CNC. tensile modulus strength increased 40% 25%, respectively, composite CNC, WVP decreased 25% after formation nanocomposite 3 obtained can be used a reinforcing agent for preparation bio-nanocomposites, have high potential development completely biodegradable food packaging materials.
