Liquidambar Formosana is a member of the maple family, featured by its maple-like leaves and spiny cones. In this study, we focus on the mechanical property and humidity-triggered reaction of its cone. The cone is composed of three parts: the spiny outer shell, the beak-like corks that serve as seed carriers and the buckyball-like structure which supports the whole structure. Microstructure features of the cone are characterized by micro-CT and SEM and the mechanical properties were measured by compression tests. The cone consists of well-organized open cell foams which provide high specific strength and prevent buckling under compression. Additionally, the humidity-triggered shape change is investigated. The corks open when cone is dried and close when the humidity increases, which facile the conservation and spreading of seeds. These unique characteristics show great potential in the designs of novel light-weight, anti-buckling composites, and drug delivery devices and bio-inspired architectures.
