Latest Patents
Youngman Yoo holds a patent for "Functionalized cellulose nanocrystal materials and methods of preparation." This patent describes a green process for the surface hydrophobization of cellulose nanocrystals (CNCs) using carboxylic acids, biodiesel, or plant oils. The method employs an aqueous lactic acid syrup as a solvent, which not only stabilizes the water suspension of CNCs but also participates in esterification reactions. This results in the production of polylactic acid (PLA) oligomer grafted CNCs (CNC-g-PLA). The process allows for an efficient in situ solvent exchange from water to lactic acid, facilitating a subsequent esterification reaction without the need for prior drying of the CNCs. Additionally, the method promotes the reuse of reagents, thereby reducing production costs and enhancing sustainability.
