Abstract Some of the most abundant biomass on earth is sequestered in fibrous biopolymers like cellulose, chitin, and silk. These types natural materials offer unique striking mechanical functional features that have driven strong interest their utility for a range applications, while also matching environmental sustainability needs. However, these material systems are challenging to process cost‐competitive ways compete with synthetic plastics due limited options thermal processing. This results dominance solution‐based processing biopolymers, which presents challenges scaling, cost, consistency outcomes. new opportunities utilize as well fibrillation approaches, can drive renewed bridge this gap between plastic holding goals critical long‐term successful

Published: Dec. 12, 2021

As the most abundant natural polymer, cellulose is a prime candidate for preparation of both sustainable and economically viable polymeric products hitherto predominantly produced from oil-based synthetic polymers. However, utilization to its full potential constrained by recalcitrance chemical processing. Both fundamental applied aspects dissolution remain active areas research include mechanistic studies on solvent–cellulose interactions, development novel solvents and/or solvent systems, optimization conditions, various cellulose-based materials. In this review, we build existing knowledge dissolution, including structural characteristics polymer that are important (molecular weight, crystallinity, effect hydrophobic interactions), evaluate widely used non-derivatizing (sodium hydroxide (NaOH)-based N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl), N-methylmorpholine-N-oxide (NMMO), ionic liquids). We also cover subsequent regeneration solutions these into architectures (fibers, films, membranes, beads, aerogels, hydrogels) review uses materials in specific applications, such as biomedical, sorption, energy uses.

Abstract The development of flexible conductive elastomers integrating renewable feedstock, splendid mechanical property, and excellent weather resistance is major interest challenge. Here, a novel strategy reported to construct the liquid‐free cellulose‐derived ionic elastomer that successfully applied in wearable sensor triboelectric nanogenerators (TENG). In this strategy, with physical chemical dual‐crosslinking network prepared via situ polymerization polymerizable deep eutectic solvent. construction improves strength toughness more than 2 times, cellulose contributes forming dense hydrogen bond crosslinking can improve recyclability, anti‐freezing, solvent‐resistance performance. Benefiting from these features, sensors TENG for monitoring human motion, harvesting energy convert into stable electrical outputs light LEDs, charge capacitor, power electronic watch. maintains reliable sensing performance even after recycling, soaking organic solvent, or at low/high temperature. This study paves promising fabricating sustainable multifunction electronics are suitable harsh environments.

Tough and Ultrastretchable Liquid‐Free Ion Conductor Strengthened by Deep Eutectic Solvent Hydrolyzed Cellulose Microfibers

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 32(29)

Published: May 3, 2022

Abstract Ion conductors (ICs) have gained extensive research interest in various advanced application scenarios including sensors, batteries, and supercapacitors. However, stretchable, tough, long‐term stable ICs are still hard to achieve yet highly demanded. In this study, the authors propose a one‐pot green sustainable fabrication of cellulose based through polymerizable deep eutectic solvents treated followed by an situ photo‐polymerization. The obtained exhibit extremely high stretchability (3210 ± 302%), toughness (13.17 2.32 MJ m −3 ), transparency, self‐healing ability. Notably, introduction fibers greatly enhances mechanical properties while eliminating environmental concerns traditional nanocellulose process. More importantly, possess good performance stability after 1 month storage. Due these outstanding properties, feasibility applying human motion sensing physiological signal detecting is demonstrated. This simple method will contribute development self‐healing, transparent, ICs.
