Herein, lignocellulosic nanofibrils (LCNF) suspension containing 0.1, 3.9, and 17.2 wt% lignin were utilized to fabricate films by filtration and pressing process. The stiff nature of fibrils containing lignin made them less able to conform during filtration, resulting in more uneven surface structure with higher roughness value. Lignin in the films interfered in hydrogen bonding between cellulose...
Pineapple peel is a renewable agricultural residue available in abundance whose multipurpose utilization deserves more attention. The present study aimed at the isolation of nanocellulose from pineapple peel and evaluation on its reinforcement capability for gellan gum film. The results from scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD)...
Dissolution, dispersion, and aggregation characteristics of 2-hydroxy-3-trimethylammoniopropyl polysaccharides made from β-1,3-glucan extracted from Euglena (referred to as paramylon) differing in the degree of substitution (DS) of a 2-hydroxy-3-trimethylammoniopropyl group were examined. Freeze-dried solids made from cationic paramylon derivatives with a DS ranging from 0.07 to 0.16 spontaneously...
The applications of polyvinyl alcohol (PVA) films are still hampered due to great affinity to water, poor mechanical strength and lack of biological properties. To overcome these shortcomings, this study presented a successful development of PVA films by the introductions of tannic acid (TA) and pineapple peel-derived cellulose nanocrystals (PPNc). The structure, morphology, light transmittance, water...
