Recently, researchers from University of California, HRL laboratory and California Institute of technology developed the world.

Lightest

The density of this material is 0.9 mg / ml, about 100 times lighter than that of expanded polystyrene.

"This new material has micrograms.

Cell structure

The air is 99.99%, solid is 0.01%, and the thickness of the interconnected hollow pipe lattice is 1000 times thinner than human hair.

Dr. Tobias Schaedler of HRL laboratory said.

The structure of the material has unprecedented mechanical properties, including complete recovery capacity and very high compression after compression of more than 50% tension.

energy

Absorptive capacity.

"When the actual size of the material is reduced to the nanometer level, it will become very powerful," said Lorenzo Valdevit, the project's principal investigator. "With the possibility of tailoring the microcrystalline structure, unique microporous materials can be obtained."

The material is developed specifically for the defense research advanced research division, which can be used in battery electrodes and acoustics, vibration or shock energy absorption.
