Summary: The study reveals that the molecular weight of cellulose affects solubility, orientation, and mechanical properties of the fibers. When the molecular weight of cellulose is low, the fibers exhibit high orientation and crystallinity, leading to excellent mechanical properties. However, as the molecular weight increases, solubility decreases while the orientation and crystallinity reduce, ultimately affecting mechanical properties.

Summary: The pollution caused by petroleum plastics on the environment is increasing. To address this issue, a biodegradable composite film was developed using corn starch carbamate, cellulose nanofibers (CNF) and lignosulfonate. The composite film showed improved mechanical properties, UV resistance, water resistance, and thermal stability when the degree of substitution (DS) of starch carbamate was increased. The resulting composite film with DS=0.14 exhibited better performance compared to other DS composite films, highlighting its potential as a degradable packaging material.

Summary: In this study, a glutaraldehyde-assisted crosslinking strategy was developed to prepare crosslinked regenerated cellulose (CRC) films, and the effects of different crosslinking methods on the dielectric and mechanical properties of the films were investigated. The CRC films showed reduced defects and enhanced intermolecular interaction compared to common RC films. With a glutaraldehyde concentration of 6 vol% and a crosslinking time of 30 min, the CRC film exhibited the lowest dielectric loss and the highest breakdown strength, as well as high tensile strength and excellent tensile modulus. This work provides new insights for tailoring the properties of cellulose films and has significant implications for the fabrication of high-performance cellulose-based dielectric materials.

Summary: The study investigates different pre-treatments for pre-consumer textiles to meet specific parameters for fiber production. Pre-treatments were able to make uncolored textiles suitable for both cold NaOH(aq) and cellulose carbamate processes, while colored textiles were only suitable for the cellulose carbamate process after pre-treatment. Further optimization of regeneration steps is expected to improve mechanical properties of the fibers produced.

Summary: Environment-friendly dielectric materials with high charge-discharge efficiency and energy density are urgently needed in the field of energy storage. Cellulose, with advantages of renewability, non-pollution, wide source, and cheapness, is a potential candidate. In this work, polyvinylidene fluoride (PVDF) was employed to reduce the hydrophilicity of cellulose. By preparing regenerated cellulose (RC)/PVDF dielectric composite films (RC-PVDF) via immersion method, the energy storage density of RC-PVDF reached 8.3 J/cm3 under the electric field of 410 MV/m, which was significantly higher than that of RC and PVDF. This study expands the application of cellulose in humid environments and provides a promising option for the development of high-performance biopolymer-based dielectric materials.
