Herein, the marine source polymer, chitosan (CS), was utilized to fabricate bionanocomposites by mussel-inspired sonochemical assisted method. The surface modified nanofillers as active ingredients were provided by assembling biomimetic polydopamine (PDA) onto the CeO nanoparticles through redox polymerization as a surface modification technology. Standard spectroscopic methods were used to characterize the resulting cerium oxide PDA-treated nanoparticles (NPs). CeO/PDA/CS nanocomposites (NC)s were manufactured using a sonochemical process by inserting nanostructured fillers into the CS polymer matrix. The morphological features and structural characteristics of NCs were considered using field emission scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and thermogravimetric analysis techniques. It was found that based on the biomimetic PDA layer the hydrogen bond interactions between CS biopolymer functional units with PDA functional units have occurred. Therefore, a pleasant distribution of surface adapted NPs in macromolecular matrix in the form of nanostructured composites was observed.

在此，利用海洋来源的聚合物壳聚糖（CS），通过受贻贝启发的声化学辅助方法制备生物纳米复合材料。作为活性成分的表面改性纳米填料是通过氧化还原聚合作为表面改性技术将仿生聚多巴胺（PDA）组装到CeO纳米颗粒上。使用标准光谱方法来表征所得氧化铈 PDA 处理的纳米颗粒 (NP)。 CeO/PDA/CS 纳米复合材料 (NC) 是通过将纳米结构填料插入 CS 聚合物基体中，使用声化学工艺制造的。使用场发射扫描电子显微镜、X射线衍射、傅里叶变换红外光谱、透射电子显微镜和热重分析技术来研究NC的形态特征和结构特征。结果发现，基于仿生PDA层，CS生物聚合物功能单元与PDA功能单元之间发生了氢键相互作用。因此，观察到表面适应的纳米粒子以纳米结构复合材料的形式在大分子基质中良好的分布。
