Methyl cellulose/cellulose nanocrystal nanocomposite fibers with high ductility

摘要: Abstract Methylcellulose/cellulose nanocrystal (MC/CNC) nanocomposite fibers showing high ductility and modulus of toughness were prepared by a simple aqueous wet-spinning from corresponding hydrogels into ethanol coagulation bath followed drying. The hydrogel MC aq. concentration was maintained at 1 wt-% while the CNC loading systematically varied in range 0–3 wt-%. This approach resulted MC/CNC fiber compositions 25/75 wt-%/wt-% to 95/5 wt-%/wt-%. optimal mechanical properties achieved with composition 80/20 wt-%/wt-% allowing strain (36.1%) (48.3 MJ/m3), still keeping strength (190 MPa). Further, we demonstrate that continuous spinning is potentially possible. results indicate possibilities spin MC-based highly ductile composite environmentally benign solvents.
