主　　题：Lignin nanocellulose deep eutectic solvent bamboo saturated steam heat treatment parenchyma 

摘      要：Bamboo vascular bundle fiber and parenchyma(BP)are separated by high-temperature treatment with saturated *** vascular bundle fiber is widely used in the market,but how to develop and utilize parenchyma tissue is a difficult *** sulfated cellulose nanofibers(ANFs)were obtained by sulfating BP with a deep eutectic solvent(DES),which provided a theoretical basis for the value-added utilization of *** DES as the reaction medium and reagent,the BP was grafted with a sulfonic acid group to form a gel substance in water,ANFs and nanocellulose gel were obtained by ultrasonic cell *** highest yield of ANFS was 75%.The width of the ANFs was about 3 nm,and a small number of nanofiber aggregates existed at the same time.A high aspect ratio of ANFs,due to their high viscosity,has potential applications as enhancers at low *** acid(ZnCl 2)added based on binary(DES)greatly improved the thermal stability of the ANFs and maintained the crystal form of cellulose I.
