Abstract:
      Using Bambusa emeiensis L. as the raw material， lignin-containing cellulose nanofibril （LCNF） were prepared from it through pretreatment with a ternary acidic deep eutectic solvent （DES） composed of choline chloride， glycerol， and p-toluenesulfonic acid， followed by high-pressure homogenization. The removal behaviors of the major components of fiber from Bambusa emeiensis L. during acidic DES pretreatment were investigated， and the effects of lignin content on the physicochemical properties of LCNF were systematically evaluated. Pearson correlation analysis was further employed to quantify the relationships among the different properties. The results showed that the lignin removal rate of fiber from Bambusa emeiensis L. reached 84.7% after DES pretreatment. With decreasing lignin content， the average width of the resulting LCNF decreased from 24.47 nm to 19.95 nm， while the crystallinity index increased from 60.2% to 67.6%. The maximum thermal degradation temperature ranged from 330 ℃ to 350 ℃. The rheological analysis revealed that the LCNF suspensions exhibited shear-thinning behavior and a typical “solid-like” gel network characteristic. Pearson correlation analysis showed a strong positive correlation between lignin content and the average LCNF width （r = 0.98）， and a highly negative correlation between lignin content and crystallinity index （r = -0.88）.
