摘　　要：以氧脱木素后硫酸盐蔗渣浆为原料,研究了臭氧处理前后纸浆性能及纤维微观形貌的变化。结果表明,臭氧处理后纤维表面出现大量沟壑,说明纤维结合力有所降低,即臭氧处理促使纤维之间氢键的联接断裂。此外,纸浆的黏度、卡伯值随着臭氧处理的强度增加呈现下降趋势,结晶度和羧基含量较处理前有明显增加,为进一步制备纳米纤维素提供有利条件。The effects the ozone oxidation on the kraft bagasse pulp properties and the microstructure of the fibers were studied. The results show that there is a large amount of gully on the surface of the fiber after ozonation which indicats that the fiber binding force is reduced, that is, ozone bleaching can promote fracture of the hydrogen bond between the fibers. In addition, with the increase of the intensity of ozone oxidation, viscosity, Kappa number showed a downward trend, crystallinity and carboxyl content increased significantly, which benefits to the nano - cellulose preparation.
