The regenerated cellulose films were successfully prepared using different ionic liquids including AmimCl, BmimCl, EmimCl, and EmimAc as solvents. It was shown that the regenerated cellulose films displayed smooth, highly uniform, and dense morphology properties. 13C CP/MAS NMR spectra and XRD corroborated that the transition from cellulose I to II had occurred after preparation. In comparison, the ionic liquid EmimAc possessed much stronger dissolubility for cellulose and the cellulose film regenerated from ionic liquid EmimCl exhibited the most excellent tensile strength. The notable properties of the regenerated cellulose films are promising for applications in transparent, biodegradable packaging and agricultural purpose as a substitute for PP and
PE.
