breakthrough t-shirt supermaterial is like wearing nothing at all
In fact, the temperature is about 4 degrees Fahrenheit lower than that of ordinary cotton.
Team of material scientists led by Po-
Chun Hsu of Stanford University has developed a plastic fabric that will keep your skin very cool. It\'s hyper-
It\'s breathable for both water vapor and infrared radiation, and the harmless energy your body releases is heat, which means that the fabric can let your body release heat as if you didn\'t wear anything.
Scientists today outlined their material breakthroughs in a paper in the journal Science.
How efficient is Hsu material? A three-
Heat your skin with just 1 layer. 4 degrees.
In contrast, thin cotton T-
The shirt will heat your skin.
1 degree while other commercial plastic textiles can raise your temperature by 5 degrees. 2 degrees.
The difference is impressive.
Cooling and efficient textiles like Xu\'s can have a huge impact beyond fashion or sportswear.
\"If you can cool this person down rather than cool down the buildings they work or live in, it will save energy,\" said Yi Cui, a researcher at Stanford University\'s team.
According to Svetlana Boriskina, a material scientist at MIT, he is not involved in the development of this new material, which may have a huge impact on indoor cooling.
Depending on the cooling system and the building, lowering the air conditioner by two to seven degrees can save up to 45% of the energy.
Just like the opposite side of the space blanket, Imagine Xu\'s new fabric.
The space blanket is usually used for first aid, it is thin, but can heat you quickly by stopping two types of heat loss.
First of all, they can prevent your body from vaporizing sweat from the skin, one of the most effective ways for humans to cool themselves.
Any kind of blanket or non-blanket is basically the same
Clothes that can be breathable.
But the space blanket is like a hot summer.
Shield, the second way also warms you.
They reflect warm, continuous infrared radiation back to your body.
Infrared radiation is the form of heat we send out.
When you sit down, you emit 40 to 60% of the heat as infrared radiation.
This is what the thermal goggles see.
At the same time, the fabric of the Hsu is exactly the opposite, as it does not prevent any natural cooling method.
This new fabric is like cotton, breathing.
It allows water vapor to easily squeeze through many pores of the material.
The new thing is that the material also allows 96% of the infrared radiation to pass through it without hindrance.
This is because this material is made of plastic that we use as adhesive
Wrapped in the kitchen, there is a molecular structure that allows infrared radiation to pass through, just as the light passes through the glass.
A big problem with Xu\'s team is that the plastic is naturally transparent. Wearing see-
Wearing clothes is not exactly the same as our concept of modesty in the 21 st century.
Fortunately, Xu\'s team was able to use a variant of the plastic commonly used in the battery industry, which is opaque
Although a little ugly color. Think wax-paper beige.
Still, there are a few issues with Xu\'s cooling material that might give-be clothing-makers pause.
Now, the beige one will stay.
When you dye or color a material, you are changing its molecular structure, which may effectively destroy the fabric\'s ability to absorb infrared radiation so easily.
The shirt may unnecessarily warm you up in hot weather, and it is also soft and flexible.
Xu\'s material is a little rough, plastic-y feel to it. Still-
When you\'re so cool, maybe you don\'t care who\'s laughing at your crumpled beige shirt.
