dc.description.abstractHYDROGELS OF TEMPO-OXIDIZED NANOCELLULOSE WERE STABILIZED FOR DRY-JET WET SPINNING USING A SHELL OF CELLULOSE DISSOLVED IN 1,5-DIAZABICYCLO[4.3.0]NON-5-ENIUM PROPIONATE ([DBNH][CO2ET]), A PROTIC IONIC LIQUID (PIL). COAGULATION IN AN ACIDIC WATER BATH RESULTED IN CONTINUOUS CORE-SHELL FILAMENTS (CSFS) THAT WERE TOUGH AND FLEXIBLE WITH AN AVERAGE DRY (AND WET) TOUGHNESS OF ?11 (2) MJ·M-3 AND ELONGATION OF ?9 (14) %. THE CSF MORPHOLOGY, CHEMICAL COMPOSITION, THERMAL STABILITY, CRYSTALLINITY, AND BACTERIAL ACTIVITY WERE ASSESSED USING SCANNING ELECTRON MICROSCOPY WITH ENERGY-DISPERSIVE X-RAY SPECTROSCOPY, LIQUID-STATE NUCLEAR MAGNETIC RESONANCE, FOURIER TRANSFORM INFRARED SPECTROSCOPY, THERMOGRAVIMETRIC ANALYSIS, PYROLYSIS GAS CHROMATOGRAPHY-MASS SPECTROMETRY, WIDE-ANGLE X-RAY SCATTERING, AND BACTERIAL CELL CULTURING, RESPECTIVELY. THE COAXIAL WET SPINNING YIELDS PIL-FREE SYSTEMS CARRYING ON THE SURFACE THE CELLULOSE II POLYMORPH, WHICH NOT ONLY ENHANCES THE TOUGHNESS OF THE FILAMENTS BUT FACILITIES THEIR FUNCTIONALIZATION.
