Abstract
A method of manufacturing a polymer coated cellulose nanocrystal composite material begins with an aqueous cellulose nanocrystal (CNC) suspension mixture. The aqueous CNC suspension mixture is dried to remove the liquid solvent from the aqueous CNC suspension mixture to form a dry CNC powder. Diethylenetriamine (DETA) is combined with melted Maleated-anhydride Polypropylene (MAPP) to form a DETA-functionalized MAPP (MA) mixture. The MA mixture is cooled and pelletized to form MA pellets. The MA pellets, the dry CNC powder, and a neat polypropylene (PP) are combined to form a CNC-PP mixture. The CNC-PP mixture is compounded by melting, subsequently cooled and pelletized to form CNC-PP pellets.
