Scientists have created a new material for a "space blanket" podsmotrev idea from squid
Engineers from the University of California at Irvine (USA) have developed a material on the basis of which it will be possible to produce a new generation of space blankets that can control how much heat passes through them, says EurekAlert. An article in the journal Nature Communications, describes the innovative development indicates that researchers "assembled" appropriate technology in marine life - cuttlefish, squid and octopus, with the ability to instantly change the color of their skin at risk masquerading as relief.
"Ultra Space blankets have long been used on Earth. They are often used by marathon runners, allowing the body to runners after a long run to keep the remaining heat. However, the key disadvantage of such blankets is the static nature of the material from which they are made. It does not allow to adjust the level of heat transfer ", - says co-development Gorodetsky Alon, Associate Professor, Department of Chemistry and Biomolecular Engineering Institute of California, Irvine (UCI).
"We have created a new version of the material, which feature is the ability to change its properties, which allows to adjust the delay or release of heat," - adds the scientist.
The researchers took as a basis for design of the skin of several different types of squid, octopus and cuttlefish, which uses an adaptive, dynamic skin for the existence of water. The unique ability of the cephalopod masquerade rapidly changing color is partly due to the skin cells called chromatophores that can change its shape instantly.
"We used a similar concept in its design, creating a layer of material in tiny metal" islands "that are adjacent to each other. In a relaxed state "islands" are merged together, and the material reflects and traps heat. When the material is stretched, the "islands" of drifting apart, letting in more heat, "- explains PhD student Department of Chemistry and Biomolecular Engineering at the UCI Eric Leung.
The developers believe that their material will be able to find its application not only in the production of heat management blankets. For example, it can be used for the production of reflective inserts in buildings to create an insulating layer adapted to different environmental conditions; for the manufacture of tents that would be extremely good for the comfort the inhabitants in the open air; material may also be used to effectively control the temperature of electronic components. In addition, the new material is perfect for creating clothes.
"Everyone fits their own room temperature. One can be comfortable at 18 degrees Celsius, the other feels good only at 25 degrees. Our invention will allow to develop clothing that will provide comfort to every person in the same room. In addition, it can lead to potential savings of 30-40 percent on energy costs for heating and air conditioning, "- the researchers explain.
As for the runners of the same, then they can develop a new generation of heat management blankets, equipped with special touch screen, allows you to customize your comfort temperature. By the way, the idea may well have become interested in the company Under Armour Inc. - the manufacturer of sportswear, which cooperates with the developers of the new material.
Eric Leung added that the material was very easy, durable, simple and at the same time cheap to manufacture.
