  • Publication number: 20230115147
    Abstract: The present disclosure provides to a novel continuous processing method to prepare sheets comprising cellulose nanofibril (CNF) and carboxymethyl cellulose (CMC). Single screw extrusion was utilized to continuously process mechanically fibrillated cellulose nanofibrils (CNF) into sheets. Water-retention ability and stability of CNF suspensions containing different processing aids was assessed through centrifugation and zeta potential analysis. Subsequently, highly loaded pastes (up to ˜25 wt. % total solids content) containing the best performing processing aids (carboxymethyl cellulose (CMC), xanthan gum (XG), and anionic polyacrylamide (aPAM)) and CNF were prepared using a Brabender with Banbury mixer-head at a dry weight ratio of either 0.1 to 1 or 0.15 to 1, respectively. Validation of the mixing procedure proved that highly loaded CNF pastes can be processed in under 40 minutes, saving up to 40 days in preparation and drying time.

  • Patent number: 10669404
    Abstract: The surface hydrophobization of cellulose nanocrystals (CNCs) by carboxylic acids, biodiesel, or plant oils was conducted via there herein disclosed green process using an one-pot synthetic method. In the process, an aqueous lactic acid syrup served as a solvent to provide a stable and well-dispersed water suspension of CNCs and participated in esterification reactions to produce an intermediate product of polylactic acid (PLA) oligomer grafted CNCs (CNC-g-PLA). This solvent and intermediate product system allows for an in situ solvent exchange from water to lactic acid without prior drying of the CNCs and a subsequent efficient esterification reaction of CNCs with carboxylic acids or esters having a long hydrocarbon chain (FAs). Another advantage of the disclosed process is the ability to reuse the reagents in the subsequent reaction in order to reduce the production cost.
