Abstract:
Dissolution of bacterial cellulose (BC) in room temperature ionic liquid was studied as a green solvent, and the dissolving process was observed by the polarizing microscope. The structure of regenerated bacterial cellulose was characterized by TGA and FT-IR to probe into the possibility of dissolution and regeneration of BC in room temperature ionic liquid. Results show that 1-allyl-3-methylimidazolium chloride([AMIM]Cl) is good and direct solvent for bacterial cellulose without reaction of other derivative. The thermal stability of regenerated bacterial cellulose is good, and the ionic liquid can be recycled.
