Deionized water was used as an anti-solvent for regenerating cotton cellulose from the IL.
Fifty milliliters of anti-solvent were added to the cotton/ IL solution with vigorous stirring,
and a precipitate immediately formed.
The precipitate was collected by centrifugation at 2200g for 10 min and washed with deionized water 5 times under vigorous mixing.
cotton cloth was placed in 20 mL
