By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent.
It's made of layers of clay nanosheets and a water-soluble polymer that shares chemistry with white glue.
Engineering professor Nicholas Kotov almost dubbed it "plastic steel," but the new material isn't quite stretchy enough to earn that name. Nevertheless, he says its further development could lead to lighter, stronger armour for soldiers or police and their vehicles. It could also be used in microelectromechanical devices, microfluidics, biomedical sensors and valves and unmanned aircraft.
Kotov and other U-M faculty members are authors of a paper on this composite material, "Ultrastrong and Stiff Layered Polymer Nanocomposites," published in the Oct. 5 edition of Science.

A series of lectures and discussions on the subject of Space Materials for High Temperature Applications will be taking place from 26. to 27. June 2007, at the Politecnico di Torino in Turin, Italy. The Extremat Consortium, together with the Bayern Innovativ GmbH, Department BayTech, would like to invite interested scientists to this event, as well as manufacturers and users of extreme materials.
For this purpose, the state of the art will be presented by material producers, researchers and end users, with particular reference to thermal protection systems of re-entry vehicles. The utilization of specific techniques will be discussed, together with facilities for testing materials under conditions simulating the extreme environment of space. This event will offer the opportunity of debating the most recent advancements in space materials and the prospects for the future.
This workshop is being organized in conjunction with the Extremat Consortium as a training activity within the framework of the Integrated European Project ExtreMat, with financial support from the European Community.
