Nanotechnology engineering will lead to revolutionary materials like transparent 'plastic steel'

Abstract:
Individual nanoscale building blocks, such as nanoparticles, nanosheets, nanowires or nanotubes display unique and unusually impressive mechanical properties. These mechanical properties of nanomaterials cannot be extrapolated from their bulk properties and scientists are still busily exploring the nanoscale behavior of various materials. Once the nanoscale properties of a material are known, the next problem is how to practically exploit certain properties and transfer them back into a macro structure of a bulk material. Materials engineers would love to transfer the exceptional mechanical properties such as tensile strength and Young's modulus (a measure of stiffness that reflects the resistance of a material to elongation) of nanoscale materials into nanocomposites that then cold be used to build much tougher, lighter and flexible materials than anything we know today - say a paper thin sheet of nanocomposite material that is transparent, flexible, yet as strong as steel. So far, effective load transfer and homogenous dispersion appear to be the key issues in order to take advantage of the extraordinary properties of nanomaterials for mechanical reinforcement applications. New research coming out of the University of Michigan has resulted in nanocomposite materials with a very high content of inorganic component and nearly perfect stress transfer. The stiffness and tensile strength of these multilayer composites are an order of magnitude greater than those of analogous nanocomposites at a processing temperature that is much lower than those of ceramic or polymer materials with similar characteristics.
