Structure-property relations in biological composite materials: An inspiration source for synthetic materials — •Helge-Otto Fabritius¹, Joachim Enax², Xia Wu³, Matthias Epple², and Dierk Raabe¹ — ¹Max-Planck-Institut für Eisenforschung, Düsseldorf, Germany — ²University of Duisburg-Essen, Essen, Germany — ³University of Paderborn, Paderborn, Germany

From a materials science point of view, biological materials are hierarchically structured nano-composites optimized through evolution to perform vital functions within the specific eco-physiological strains of living organisms. Most of them consist of a matrix of structural biopolymers like collagen in vertebrate bones and teeth, chitin in arthropod exoskeletons, or cellulose in plants and various other organic and inorganic constituents. Their physical properties are adapted to the specific functions of the materials and can be very diverse, which is caused by structural and chemical alterations at different hierarchical levels. Understanding the structure-property relations and thus the design principles of biological materials is a valuable source of inspiration for the development and improvement of synthetic materials with tailored properties. Using a combination of experimental and theoretical approaches, we explore this potential in a variety of natural materials like shark tooth enameloid as a biological model for dental materials with improved performance and durability and photonic crystals formed by the arthropod cuticle as inspiration for the development of new, optically active materials.
