All-cellulose Composite Reinforced with Cellulose Nanofibrils Isolated from Banana Rachis

摘要：

　　All cellulose composites (ACCs)were fabricated by regeneration of cellulose matrix in Lithium chloride/N, N-dimethylacetamide(LiCl/DMAc) and reinforced with cellulose nanofibrils(CNFs) isolated from banana rachis by enzyme hydrolysis.The furnished cellulose nanofibrils had a diameter of (16 ± 3.46) nm, a length of (985.6 ± 136.1) nm and an aspect ratio of 61.9.Incorporating of the CNFs in the regenerated cellulose matrix improved the tensile propertiesmarked byan increase in the stress at break from 35.53 to 66.45 MPa for 0wt% and 20 wt% CNFs loading respectively, this consequently made the films stifferrecording an increase in youngs modulus from 0.68 to 3.25 GPa and dwindling in strain to fail from 47.63% to 16.8%.Optical transmittance also decreased with increasing CNFs content from 86.88% to 68.11% when the CNFs loading was increased from 5% to 20%.
