Özet

This paper reports the engineering of large area cellular solids with controllable stiffness and specific strengths up to 230 MPa/(Mg/m(3)), which is stronger than most high strength alloys including 4143 steel and Ti-6Al-4V. The high strength arises from the size-based strengthening of the mn-sized struts. The cellular solid's porosity can be varied from 30 to 90% to control the specific stiffness from 4 - 20 GPa/(Mg/m(3)). The cellular solid's regular microporous architecture and self assembly based fabrication allow nanometer to micrometer control over the hierarchical geometry and chemistry, which enable large area materials with high strength and controllable stiffness.
