Lignocellulose-Based Nanocomposites

The focus on environmental safety is leading to the attention in the advancement of renewable resource-based composite materials. Lignocellulosic materials (cellulose, hemicellulose, and lignin) are important bioresources found abundantly in nature. In the past, lignocellulosic materials were disposed of as wastes; however, they now hold great importance in modern life, offering a vital source of renewable resources. Utilizing these resources not only reduces dependency on fossil resources effectively but also contributes to environmental protection. Recently, new types of environmentally friendly solvents, ionic liquids, have been employed for dissolving and processing these bioresources. In this chapter, we summarized the recent advancements in processing, characterization, and properties of lignocellulosic nanocomposites. Nanomaterials differ from bulk materials primarily due to two primary factors: first one, the increased relative surface area, which enhances the quantum effects and reactivity resulting from modifications in optical, mechanical, electrical, and thermal characteristics. Additionally, combining nanoparticles with polymers creates a pathway for a wide variety of established and innovative applications. An overview of extraction procedures, especially from plant-based, bacterial sources and nanomaterial, has been provided here. Challenges and future research direction in the field of lignocellulosic materials will also be discussed in this chapter.
