Broadband light trapping effect and arrays of sub-wavelength textured structures based on the butterfly wing scales are applicable to solar cells and stealth technologies. In this paper, the fine optical structures in wing scales of butterfly Papilio peranthus, exhibiting efficient light trapping effect, were carefully examined. First, the reflectivity was measured by reflectance spectrum. Field Emission Scanning Electronic Microscope （FESEM） and Transmission Electron Microscope （TEM） were used to observe the coupling morphologies and structures of the scales. Then, the optimized 3D model of the coupling structure was created combining Scanning Electron Microscope （SEM） and TEM data. Afterwards, the mechanism of the light trapping effect of these structures was analyzed by simulation and theoretical calculations. A multilayer nano-structure of chitin and air was found. These structures are effective in increasing optical path, resulting in that most of the incident light can be trapped and adsorbed within the structure at last. Furthermore, the simulated optical results are consistent with the experimental and calculated ones. This result reliably confirms that these structures induce an efficient light trapping effect. This work can be used as a reference for in-depth study on the fabrication of highly efficient bionic optical devices, such as solar cells, photo detectors, high-contrast, antiglare, and so forth.

Biomaterials have attracted more attention from biomedical research in recent years. Yet there are still unmet demands for current biomaterials, such as the reduction of local inflammation of the implantation site. Poly-Propylene Carbonate （PPC）, a polymer with ester bonds on COz backbone, degrades to CO2 and water, which are natural components of human body, yielding less inflammatory response than traditional biomaterials. However, the tensile strength and heat resistance properties of PPC are less ideal. In order to improve the properties of PPC, we have developed a new PPC （M-PPC）, modified by mixing with Poly-3-Hydroxybutyrate （PHB）. Here, we report the biodistribution profiles of PPC and M-PPC, their biocompatibility and toxicity. 125I-radiolabeled PPC and M-PPC were prepared and their biodistribution in Balb/c mice were investigated. Then acute systemic toxicity and haemolysis assays were conducted to study their toxicity and biocompatibility respectively. Results show that M-PPC has a good potential to be used as bone repair materials because it possesses typical biodistribution pattern in major organs, minimal toxicity and good biocompatibility.

It is known that the tribological behaviors of snake skins are contributed by the synergistic action of multiple factors, such as surface morphology and mechanical properties, which has inspired fabrication of scale-like surface textures in recent years. However, the coupling effect and mechanism remain to be elucidated. In this work, the morphology and mechanical properties of the scales from different body sections （leading body half, middle trunk and tailing body half） and positions （dorsal, lateral and ventral） of Boa constrictor and Eryx tataricus were characterized and compared to investigate the corresponding effects on the tribological behaviors and to probe the possible coupling mechanism. The morphological characterizations of scanning electron microscopy and atomic force microscopy revealed sig- nificant differences between the two species that the scales from Boa constrictor are rougher in general. The mechanical properties measured by nanoindentation corroboratively demonstrated substantial differences in elastic modulus and hardness. Interestingly, the ventral scales with lower surface roughness, together with relatively larger elastic modulus and hardness, manifest higher friction coefficients. A ＂double-crossed＂ hypothesis was proposed to explain the observed coupling effect of morphology and mechanical properties on friction, which may afford valuable insights for the design of bionic surface with desirable tribological performance.

Natural composites have inspired the fabrication of various biomimetic composites that have achieved enhancement on certain mechanical performance. Herein, a facial approach enabled by recent advances in polyimine chemistry has been developed to fabricate bio-inspired hard-soft-integrated copolymers from two polyimines （i.e. PI-H and PI-S） with hardness differential. Subsequent evaluations of multiple mechanical properties on the bio-inspired copolymers with PI-S contents of full-range variability （0 wt%-100 wt%） have revealed extremal transitions for friction coefficients, impact strengths and tensile moduli. More interestingly, the minimum points of friction coefficients show a deformation-resisting response toward the change of applied loads, but not for the altered sliding speeds, suggesting a more significant role of load in determining the optimal anti-friction composition of the hard-soft integrated copolymers. These trends have been further corroborated by scanning electron microscopy of the worn specimens. Together these results have demonstrated that full-range extremal tran- sitions exist on multiple mechanical properties for hard-soft-integrated copolymers, providing valuable insights to the design and fabrication of composite polymers for many applications. The polyimine-based approach outlined here also affords a convenient method to tune the ratio of two components in the copolymers within the full range of 0 wt%-100 wt%, enabling quick integration with high content variability.
