[Abstract]:Using ionic liquid 1 Ding Ji 3 methyl imidazole chloride {[BMIM] Cl} to dissolve cotton stalk fiber (CSF) into solvent, cotton stalk skin fiber was used as reinforcement material and the prepared solvent was used to prepare holocellulose composite (ACC). The effects of temperature and cellulose mass fraction on the viscosity and mechanical properties of cellulose / [BMIM] Cl system were investigated. The dissolution of cotton stalk fiber and the structure of composite material were characterized by polarizing thermostat microscope and scanning electron microscope (SEM) X-ray diffraction (XRD) FT-IR. The results show that the viscosity of cellulose / [BMIMI] Cl system increases sharply with the increase of cellulose mass fraction at the same temperature, and decreases with the increase of temperature at the same mass fraction. When the temperature is 105 鈩，
