中文摘要:

      纤维素纳米球（CNS）是一种新型的纳米纤维素材料，由于其比表面积大、粒径均匀、生物相容性好等性质而被应用于Pickering乳液稳定剂、医药、载体材料等领域。CNS可以由天然纤维素制备，再生纤维素和丝光纤维素也是制备CNS的重要原料。本文总结了CNS的制备方法，包括化学法、机械法和酶解法或这些方法的组合，探讨了不同制备过程的成球机理，并综述了CNS的应用。最后，展望了CNS未来的机遇和挑战。

Abstract:

      Cellulose nanospheres （CNS） are a new kind of nanocellulose material. Due to its large specific surface area， uniform particle size， good biocompatibility and other properties， it has been used in Pickering emulsion stabilizer， medicine， carrier materials and other fields. CNS can be prepared from natural cellulose. Regenerated cellulose and mercerized cellulose can also be used as an important raw materials for the preparation of CNS. In this paper， the preparation methods of CNS， including chemical， mechanical and enzymatic hydrolysis methods， or a combination of these methods， are summarized. The pellet-forming mechanism of different preparation processes is discussed， and the applications of CNS are also reviewed. Finally， the future challenges and opportunities of CNS are prospected.
