| Abstract:In this study， AlCl3/ZnC2/H2O was used as solvent， 1，4-butanediol diglycidyl ether (BDDE) was introduced as crosslinking agent， and bleached eucalyptus as the cellulose raw material. Cellulose was dissolved and crosslinked at room temperature to prepare the cellulose film. When the amount of cellulose and BDDE are 1.5% and 1.0%， respectively， the film had the advantages of high strength， high wet stability， high transparency， and biodegradability. Its light transmittance could reach 90%. The stress-strain energies of the obtained cellulose films reached 141.0 MPa and 19.7%， respectively. Even after soaking in water for 24 h， the wet stress and strain could reach 34.7 MPa and 67.3%. After being soaked in water for 7 days， it could still maintain a stable shape， and the swelling rate was only 94%， showing excellent water resistance and being able to hold liquids such as water， milk and soy sauce for 24 h. It also showed lower water vapor permeability (615.0 g/（m2·d）) and oxygen permeability (4.15×10-3 cm3/（m2·d·Pa）). This transparent film featured high moisture stability and excellent wet strength， and had good application effect in the fields of packaging and food preservation. |
