We report a versatile method for preparing a particulate composite based on cellulose nanocrystals (CNCs) and polyethylene glycol (PEG) via the self-organized precipitation method. The particulate composite had a core–shell structure, and depending on the molecular weight of the PEG, two types of particulates could form: one with CNCs as the core and the other with CNCs as the shell.

具有可调节组分位置的纤维素纳米晶体基核壳颗粒的制备

我们报告了一种通过自组织沉淀法制备基于纤维素纳米晶体（CNCs）和聚乙二醇（PEG）的颗粒复合材料的通用方法。微粒复合材料具有核-壳结构，根据PEG的分子量，可能会形成两种类型的微粒：一种以CNCs为核心，另一种以CNCs为壳。
