Abstract
Nature is the epitome of creativity regarding the design of functional materials that can exhibit outstanding combinations of strength, toughness and stiffness that are unmatched by manmade materials. Over the last years, a significant research effort has been devoted to elucidate the microstructure and mechanisms behind these mechanical performances, in order to duplicate them in artificial materials. This material design approach, termed biomimetics, holds the promise to yield materials with remarkable properties. In this thesis, the mechanical properties (both in the macroscopic and microscopic scale) of bioinspired 3D materials, that will be fabricated with Multiphoton Lithography (MPL), will be systematically studied using nanoindentation measurements and atomic force microscopy. Multiscale additive manufacturing augmented with guided self-assembly of block copolymers and peptides will be utilized to fabricate the global optimum with complexity and properties analogous to those encountered in nature. We will systematically study the mechanical performance and evaluate the significant mechanical properties such as fracture toughness, fracture propagation, strength, stiffness, and plastic evolution, aiming to comprehend how these properties are enhanced by the hierarchical and hybrid material biomimetic design of living organisms.
