The United States Has Developed Solar Bullet Proof Clothing.

　　据国外媒体报道，近日美国科学家研制出一种新科技太阳能防弹衣，防弹能力与普通防弹衣不相上下，且利用太阳能来防弹，质地柔软如薄纸。这是纳米技术应用的最新成果。

It is understood that this bulletproof vest is made of new materials.

This material is soft as thin paper, light, super thin and strong plastic.

It is made from the nanowires of germanium, silicon, and some other fibers.

These nanowires will be woven into traditional fabrics or surround some hard plastic surround, so that they can have the same bullet proof function as Kevera and can use solar energy and other more functions.

According to Brian Korgel, the inventor of this new type of bulletproof vest, we usually use paper pressed from wood fiber, but the thin paper material of the bulletproof vest is compacted by a large number of nanowires converted from semiconductor components such as germanium and silicon to form Blaine.

Germanium is known to be brittle and hard.

In fact, the "thin paper" material made from germanium is very strong in plasticity, bending at will without fear of damage.

In particular, the individual germanium nanowires have an unexpected degree of seed setting, and even have a similar strength and weight ratio to Kevlar.

Usually, the impact force of germanium can not be affected by germanium nanowires.

However, it is not enough to make use of Ge nanowires to make bulletproof vest.

The reason why Kevlar is bulletproof is not only because of its good bulletproof performance, but also because of its strong ballistic performance.

But germanium nanowires are slightly less than Kevlar.

So Blaine and his colleagues began planning to develop another use, solar energy, with the use of semiconductor components in new fibers.

In general, germanium absorbs light that some human eyes can see and absorbs invisible infrared rays.

However, since the photovoltaic effect of germanium is far less than that of silicon, the scientists also developed a silicon nanowire similar to thin paper.

It is understood that silicon nanowires can convert more sunlight into electricity, and individual silicon nanowires are thirty-five percent stronger than germanium nanowires and are more resistant to corrosion.

In this way, the germanium silicon nanowire fabric inside the bulletproof vest and the silicon germanium nanowires around hard plastic will pform the solar energy into electrical energy, which will drive the sensors inside the bulletproof vest and some other electrical equipment to play a better bulletproof role.
