3/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.]]> 2025/10/28 19:45:41 WU Bin,LI Bin,LIANG Tingting,LI Xianchun,LI Xin,WANG Zhiguo 4true 2025/10/28 19:45:42 ZHANG Liang,LIU Chengyue,LI Nanhua,LI Lizi,KONG Yuling,WU Caiyan,SU Cuiyang,HU Zhijun,CHEN Hua,YOU Yanzhi 3true 2025/10/28 19:45:43 SHI Zhiping,WANG Yingchao,LI Kai 2true temperature of 80 ℃， pretreatment time of 60 min， and solid-liquid ratio of 1∶10. Under these conditions， the tensile index， tear index， and folding endurance of the paper was 15.8 N·m/g， 4.27 mN·m²/g and 22 times， respectively. Comprehensive structural characterization analysis showed that the cellulose crystallinity index decreased from 48.5% to 40.8%， accompanied by substantial increases in surface porosity. The above research results indicated that the ternary deep eutectic solvent system exerted an improving effect on waste paper fibers.]]> 2025/10/28 19:45:44 LI Fengfeng,CHEN Xueping,ZHAN Zhengfeng,ZHANG Zhili,WANG Yuanyuan,TONG Guolin 1true
