Regenerated　cellulose　film　is　prepared　successfully　from　sugarcane　bagasse　cellulose　in　ionic　liquid　1-allyl-3-methylimidazolium　chloride　([Amim]Cl).　Its　dissolution　process　was　viewed　by　polarizing　microscope.　Properties　and　structures　of　the　regenerated　cellulose　films　obtained　were　characterized　by　infrared　spectroscopes,　scanning　electron　microscopy,　X-ray　diffraction,　thermogravimetry　(TGA)　and　strength　test.　The　results　showed　that　[Amim]Cl　is　a　good　non-derivatizing　solvent　for　sugarcane　bagasse　cellulose　whose　crystalline　form　transformed　completely　from　cellulose　I　to　cellulose　II　after　regenerated　directly　from　[Amim]Cl　solution.　The　cellulose　film　obtained　by　regeneration　showed　a　dense　structure　and　its　thermal　stability　and　tensile　strength　could　be　up　to　292°C　and　144　MPa　respectively.　©　All　Rights　Reserved.
