This novel method utilizes reactive eutectic media to extract cellulose nanocrystals and functionalize them with positively charged functional groups in a one-step process. The eutectic medium acts as a cellulose-solubilizing agent, while a Leuckart reagent enables reductive amination of carbonyl groups in cellulose chains, resulting in water-dispersible nanocellulose products with high crystallinity.
A novel method based on the use of reactive eutectic media for the extraction of cellulose nanocrystals and their functionalization with positively charged functional groups in a one-step procedure is presented. With its ability to form strong hydrogen bonds, the eutectic medium serves as a cellulose-solubilizing agent, while the presence of a Leuckart reagent provides the reactivity toward the reductive amination of carbonyl groups in the cellulose chains. In the proposed method, amorphous cellulose domains are partially dissolved by undergoing aminolysis, resulting in the formation of water-dispersible nanocellulose products with high crystallinity.
