这项工作是一个贡献的设计，制备和表征的纳米复合材料的生物相容性组件的基础上。的组合物，填料的几何形状，和聚合物电荷的影响被强调，并揭示了它们的作用的纳米复合材料的最终性能。我们将几种生物聚合物（甲基纤维素、海藻酸钠、壳聚糖）与两种纳米粘土（高岭石片和埃洛石纳米管）复合，通过自水浇铸法制备纳米复合材料。研究了薄膜的热稳定性、表面润湿性和力学性能。SEM显微照片突出了生物复合材料的表面形态。X射线数据使我们能够将这些纳米复合材料的介观结构与性能相关联。
This work represents a contribution to the design, preparation, and characterization of nanocomposite materials based on biocompatible components. The effects of composition, filler geometry, and polymer charge were highlighted, and their role on the final properties of the nanocomposites was revealed. We combined some biopolymers (methylcellulose, alginate, chitosan) with two nanoclays (kaolinite sheets and halloysite nanotubes) to prepare nano composites by means of the casting method from water. The thermal stability, the surface wettability, and the mechanical properties of the obtained films were studied. SEM micrographs highlighted the surface morphology of the biocomposite materials. X-ray data allowed us to correlate the mesoscopic structure to the properties of these nanocomposites.
