Lightweight, elastic inorganic metamaterials: controlling flexibility and fracture toughness through hierarchical nano-architectures
Abstract
This project seeks to create a class of ultralight inorganic superstructures with tailorable super flexibility and high fracture tolerance. Ultralight and strong nanolattice material created by PI’s group has attracted much interest as they attained GPa level stiffness at a density lower than 1% of its parent material, and is able to hold more than 160,000 of their own weight.The main thrust and novelty of the proposed work lies in proliferating controlled nanoscale topologies (i.e., inverse opal, hollow tube, nano trusses) in metal and ceramic into large area, three-dimensional architectures spanning multiple structural hierarchies to offer super elasticity and fracture toughness unattainable in their intrinsic forms.
