Mechanistic Insights Into Cellulose Dissolution in Solvents for Advanced Industrial Applications: A Systematic and Bibliometric Review

Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability. This review critically examines recent mechanistic interactions between cellulose and different solvents, focusing on the green solvent known as DES, aiming to enhance industrial applications. It begins by discussing the possible conversion of cellulose nanocrystals from their different sources and the limitations of conventional solvents in dissolving cellulose. It then explores the interactions between cellulose and DES components, explaining the mechanisms that facilitate cellulose dissolution. This study focuses on the trends of DES and their role in dissolving cellulose. Bibliometric methods were employed to analyze these trends, along with identifying current research gaps, challenges and their dissolution in DES, thereby contributing to the creation of cost-effective industrial processes. Additionally, it outlines opportunities for further research and innovation in this field.
