•AmimCl and BmimCl was more suitable for preparing quality film.•A decrease of DP resulted in a higher crystallinity index.•Crystal structure governs the properties of the film. Three ionic liquids (ILs) with increasing dissolution power, 1-butyl-3-methylimidazolium chloride (BmimCl), 1-allyl-3-methylimidazolium chloride (AmimCl), and 1-ethyl-3-methylimidazolium acetate (EmimAc), were selected for cellulose dissolution and film preparation through regeneration. The physical properties of the films were investigated, and the correlation between the IL used and the film properties was evaluated. The results indicated that the superior cellulose dissolution system, EmimAc, had the most difficult regeneration process (i.e., more time was required for gel formation), followed by AmimCl, and BmimCl. On the other hand, the film produced from AmimCl had the highest crystallinity, transparency, and tensile strength, followed by the films produced from BmimCl and EmimAc. It was inferred that stronger and more ordered molecular arrangements and inter-molecular interactions preferentially occurred during cellulose regeneration from AmimCl than during cellulose regeneration from BmimCl and EmimAc.
