The intrinsic metal ions in the solvent system were effectively utilized to catalyze the polymerization of acrylamide （AM） monomer， resulting in a tight link between the polyacrylamide （PAM） network and the cellulose network. The multifunctional hydrogel with cellulose/polyacrylamide double-network was prepared. The mechanical and electrochemical properties of hydrogels were regulated by controlling the mass ratio of acrylamide to cellulose. The results showed that the metal ions in AlCl₃/ZnCl₂ aqueous system endowed the hydrogels with excellent freezing-tolerant ability （it can work normally at -45 ℃） and ionic conductivity （2.04 S/m）. The second polymerization network constructed by polyacrylamide was strategic， and effectively improved the mechanical properties of the hydrogels. Besides， the double-network hydrogels exhibited good elastic properties in 10 compression cycles， and showed strong adhesion to different material interfaces.]]> 2023/9/20 0:00:00 WANG Youlong,LI Xin,TIAN Yahui,MA Jinxia 5true in-situ as the catalyst， and LNP-based cryogel（LRF） as a precursor can be rapidly synthesized for lignin-based carbon aerogel （LRFC）. The study results showed that in-situ doped copper salt can accelerate the gelation rate of gel formation and decrease the gelation time of LRF. Herein， the gel formation of Cu（NO₃）₂ assisted LRF can be shortened to 2.5 h， and the resultant carbon aerogel （N-LRFC） had the highest microporous rate of 94.44% and pore size of 1 nm， high graphitization， and excellent electrochemical performances. At current density of 0.5 A/g， N-LRFC demonstrated exceptional electrochemical performance with a specific capacitance of up to 347.6 F/g. and the diffusion control dominated the electrochemical process.]]> 2023/9/20 0:00:00 ZHANG Yiyi,LOU Rui,CAO Qihang,NIU Taoyuan,ZHANG Bin,WEI Guodong,CHEN Haifeng 4true 2） was 75%. The excellent filtration performance of modified aerogels mainly relied on the super hydrophilicity， unique three-dimensional porous structure and abundant surface active binding sites of the material. In addition， the filtration efficiency and flux of the modified CNF aerogels were over 99% and 20.2 L/（m²·h） after 8 cycles of filtration， showing good stability and reusability.]]> 2023/9/20 0:00:00 WANG Jie,WANG Xiaotong,ZHU Gaojian,LIU Chao,WU Weibing,DAI Hongqi,BIAN Huiyang 3true 2023/9/20 0:00:00 DU Xiaoyun,XIU Huijuan,LIANG Yanbo,LI Na,WU Minzhe,LI Jinbao 2true 2023/9/20 0:00:00 LIN Jiacheng,LIN Tao,WEI Xiaoyao,LU Lulu,LIU Feiya,YIN Xuefeng 1true
