“…[1] During long-term evolution, Nature has developed lots of materials with unique hierarchical structures, such as bones and nacres, which are of superior mechanical properties and excellent biocompatibility. [7] However, application of such fluorescent composite materials in the biomedical field is limited because both the conjugated polymer and the rare-earth metal lack good biocompatibility. [2] Through duplicating the hierarchical structure of nacre, many artificial nacrelike materials have been fabricated with strong mechanical properties, [3] gas barrier properties, [4] conductive properties, [5] and so forth.…”

“…More interestingly, some fluorescent nacrelike artificial composite materials were prepared by assembling aromatic conjugated polymer and layered inorganic silicates, [6] or by assembling chitosan and layered double hydroxide containing rare-earth metal. [7] However, application of such fluorescent composite materials in the biomedical field is limited because both the conjugated polymer and the rare-earth metal lack good biocompatibility. Other traditional fluorescent materials, such as organic dyes or quantum dots, are also not good candidates in fabricating functional and biocompatible nacrelike composite materials, considering their potential toxicity.…”

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.[a] Prof.

“…Both inorganic platelets and organic components were found in these familiar hierarchical structures of the tough, strong, and stiff natural materials. Inspired by these natural materials, some high mechanical performance and multifunctional hybrid materials have been fabricated . Comparing with those common materials fabricated by general method, these hybrid materials show a remarkable increase in stiffness, toughness, and strength.…”

Inspired by many strong, toughness, and stiffness materials in nature, we first present bio‐inspired structure hybrid films fabricated by layer‐by‐layer assembly technique based on low‐surface‐energy graphite micro‐sheets and styrenic block copolymers. Compared with pure polymer films, the mechanical properties of the hybrid films have been greatly modified in failure stress, elastic modulus, and failure energy due to the rigid bio‐inspired structure. After graphite micro‐sheets surface modified by dopamine, a better enhancement in mechanical properties was achieved with the assistance of dopamine surface modification in the almost same content of inorganic component. The layer‐by‐layer assembly method was improved by introducing the wet‐coating techniques that has been widely applied in industry. This improved method is more easily to fabricate large‐area hybrid films without destroying the bio‐inspired structure of the hybrid films. This improved method and bio‐inspired structure were first applied to reinforce elastomer in this work, while this bio‐inspired structure has shown great success when applied in the area of plastic.

Layered double hydroxides (LDHs) are a class of anion‐intercalated functional materials that are also known as hydrotalcite‐like compounds. This chapter focuses on the structural properties of LDH materials and recent advances in theoretical studies of the LDHs structure. To understand the structure of LDHs, it is necessary to start from the structure of brucite [Mg(OH) 2 ], which is of the CdI 2 type, typically associated with small polarizing cations and polarizable anions. The unique structure of LDHs provides a confined microenvironment for the intercalated guest molecules and thus results in controllable structures and performances for LDHs‐based materials. Multiple quantum well (MQW) structure is an important insight to study the confinement and host‐guest interaction of LDHs. The outstanding properties of LDHs and LDH‐intercalated materials give them great potential in imaging, therapy, drug delivery, and multimodal applications.
