Abstract

Due to the inherent stability of plant cell wall structure, the utilization of various fiber raw materials is limited in terms of diversification. Therefore, it is crucial to explore a simple, environmentally friendly, and cost-effective strategy for the high-value utilization of fiber raw materials. Herein, lignocellulose nanofibrils (LCNFs) were prepared from wheat straw by a combination of high-yield pulp production technology and mechanical methods. By using the mild biochemical mechanical pulp pretreatment technology, the whole process avoids the use of other organic solvents; only recycled sodium hydroxide chemical reagents are needed. The prepared LCNFs exhibited small particle size range (< 10 nm) and high thermal stability (T_Max up to 350.8 °C). Moreover, by adjusting the front-end conditions during preparation, the properties of LCNFs films such as crystallinity, hydrophobicity, and water absorption can be controlled. Overall, this study provides a simple and efficient way for valorizing agricultural waste as well as a feasible alternative to incineration.

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
