摘要：
The dissolution of cellulose was investigated in ionic liquid [C(4)mim]Cl assisted with ultrasound irradiation. The effects of ultrasound power and irradiation duration on cellulose dissolution and the regenerated cellulose properties were discussed. The physicochemical properties of the regenerated cellulosic preparations were also characterized by FT-IR, solid-state CP/MAS (13)C NMR, wide angle X-ray diffraction and thermal analysis. It was found that the chemical structure of regenerated cellulose did not change obviously under the conditions used. It was suggested that the crystalline structure of cellulose was converted from cellulose I to the mixture of amorphous cellulose and cellulose II after dissolution and regeneration.
