Exploring the potential of lignin nanoparticles: synthesis, applications, and future directions
摘要
Lignin, the second most prevalent biopolymer after cellulose, stands out as a fascinating natural material with immense potential for diverse applications. Lignin is the common lignocellulosic biomass component although its potential as a fuel source is still little understood, leading to underutilization. This paper's objective is to look into lignin's untapped potential, especially at the nanoscale and key strategies for improved use is the effective synthesis of lignin nanoparticles, or LNPs. A systematic literature review was performed utilizing multiple scientific databases, such as Web of Science, PubMed, and Science Direct. The search focused on articles discussing nanoscale lignin, with an emphasis on efficient LNPs synthesis methods, controlled reaction time, and reduced chemical consumption. The review presents an in-depth analysis of nanoscale lignin, specifically LNPs, obtained through advanced synthesis methods. It covers different types of lignin, elucidates their applications, and identifies existing limitations. Additionally, the review explores how LNPs effectively address these limitations, encompassing preparation techniques, nanocomposite formations, and diverse applications. In summary, this review consolidates research findings from previous years, shedding light on the potential of LNPs. By addressing key research areas, challenges, and offering potential perspectives, it aims to stimulate future investigations into this promising avenue. The controlled synthesis of LNPs proves to be a pivotal strategy for expanding lignin's applications, fostering sustainable advancements in various fields.
