Cellulose hydrogels were prepared from commercial cellulose using NaOH/urea and LiCl/DMAc methods. For method, alkali hydrates (OH-(H2O)x), urea (urea(H2O)y), water adsorbed into fiber to break hydrogen bonds between molecules yielding HG_Urea. the Lithium-DMAc complexes, [Li(DMAc)n]+Cl-, seeped fibers substituted by O-H…Cl-[Li(DMAc)n]+ produce transparent gel, HGL. Both freeze-dried show chara...
