Description
Many natural and biomimetic platelet–matrix composites – such as nacre, silk, and clay-polymer – exhibit a remarkable balance of strength, toughness, and/or stiffness, which call for a universal measure to quantify this outstanding feature given the structure and material characteristics of the constituents. Analogously, there is an urgent need to quantify the mechanics of emerging electronic and photonic systems such as stacked heterostructures, which are composed of strong in-plane bonding networks but weak interplanar bonding matrices. Herein, we present the development of a unified framework to construct a universal structure-material-property diagram that decodes the interplay between various geometries and inherent material features in both platelet–matrix composites and stacked heterostructures. Validated by several 3D-printed specimens and a wide range of natural and synthetic materials across scales, this universally valid diagram has important implications for science-based engineering of numerous platelet–matrix microstructures and stacked heterostructures while significantly broadening the spectrum of strategies for fabricating new composites through incorporating contrasting platelets. Given the minisymposium theme of “… Investigation of bio-inorganic interfaces”, this work opens up several new opportunities to further extend the proposed diagram to include locking mechanisms, stacked multiheterostructures, extrinsic hierarchical toughening processes, etc., to identify and delineate new boundaries and overlaps in mechanistic processes of platelet–matrix microstructures with the goal of unveiling other mysteries in multiphase multifunctional materials.
