THE GIST:
- Artificial nacre, or mother of pearl, can now be mass-produced.
- The material is flameproof, super strong and as cheap as paper to make.
- It could be used to fireproof homes and to make cars more fuel efficient.
A
natural pearl is a rare treasure, but new mass-produced mother of pearl could soon be as cheap and versatile as paper.
Flameproof yet flexible, thinner than office paper but 20 times as strong, the new material could eventually make aircraft lighter and comfortably protect police from bullets.
"
Natural nacre is this perfect marriage of stiffness, strength and toughness," said Andreas Walther, a researcher at the Helsinki University of Technology and a co-author of a recent paper in the journal
Nano Letters.
"Our artificial nacre compares very well to the natural material."
Synthetic nacre has long been a goal for both material scientists and biologists. For material scientists man-made nacre could provide strong, lightweight, cheap and environmentally-friendly material for a huge variety of products.
For biologists, synthetic nacre would provide a new way to study the complex mesh of soft protein and hard calcium carbonate that mollusks use as protection and women as decoration.
