  Abstract

Cellulose and lignin are abundant biomass resources, but their low processability and flexibility limit their use as thermoplastic materials. This review aims to address these challenges by examining the structural characteristics of cellulose and lignin and exploring various chemical and physical plasticization strategies. For cellulose, chemical modifications such as acetylation, esterification, and carboxymethylation can reduce hydrogen bonding and enhance flexibility. Additionally, plasticizers like glycerol, ionic liquids (ILs), and deep eutectic solvents (DES) further improve chain mobility. In the case of lignin, strategies such as alkylation, acetylation, and copolymerization with polyesters or polyurethanes have been investigated to lower the glass transition temperature and achieve thermoplasticity. By combining cellulose and lignin, we can create functional composites that exhibit enhanced mechanical properties, thermal stability, and biodegradability, especially when employing compatibilizers to modify interfacial properties. Applications of these plasticized materials include thermoplastic starch (TPS) and poly(lactic acid) (PLA) composites, which show promising performance. However, commercialization still faces technical and economic challenges, such as raw material heterogeneity, the need for ecofriendly processing, property optimization, and cost reduction. Future directions include designing ionic polymers and multifunctional nanocomposites to enhance performance and scalability. Collectively, cellulose and lignin have great potential as sustainable thermoplastic alternatives.
