Inspired by the hierarchical structure of nacre, lots of functional nanocomposite films have been fabricated through finely tuning the composition and structure. To broaden their application in biological and biomedical research, it is highly demanded to develop a new strategy to fabricate nanocomposite films that are both biocompatible and functional. Herein, hyperbranched poly(amido amine)s (HPAMAMs) have been assembled with clay nanosheets. The obtained nanocomposite films show good mechanical performance and fluorescence properties. Analysis of the structure of the nanocomposite films indicates that the HPAMAMs and the clay nanosheets are stacked together in an orderly manner. The clay nanosheets align in the direction parallel to the film surface. Because of the inherent biocompatibility and autofluorescence property of the HPAMAMs, such composite films are thought to be very promising in applications requiring biocompatibility, fluorescence, and good mechanical performance. The method should provide a new route to the fabrication of functional nacrelike composite materials.
受珍珠母分层结构的启发，通过精细调整组成和结构，制备了许多功能性纳米复合薄膜。为了拓宽其在生物和生物医学研究中的应用，迫切需要开发一种新策略来制备兼具生物相容性和功能性的纳米复合薄膜。在此，超支化聚（酰胺胺）（HPAMAMs）与粘土纳米片组装在一起。所得纳米复合薄膜具有良好的机械性能和荧光性能。对纳米复合薄膜结构的分析表明，HPAMAMs和粘土纳米片以有序的方式堆叠在一起。粘土纳米片在与薄膜表面平行的方向上排列。由于HPAMAMs固有的生物相容性和自发荧光特性，这种复合薄膜被认为在需要生物相容性、荧光和良好机械性能的应用中非常有前景。该方法应为制备功能性珍珠母状复合材料提供一条新途径。
