According to the United States " discover " magazine story, the scientist invention of British London university gave a kind recently " intelligent glass " , need not air conditioning, light is glass can make indoor winter warm Xia Liang. This kind of glass can have be absorbed optionally or reflex infrared ray, maintain indoor temperature thereby comfortable and delightful.
Why " intelligent glass " have so magical effect? The scientist says, depend on daub secretly be in it is apparently ultrathin layer material -- of 2 oxidation vanadium and tungsten
Mixture. When weather is cold, 2 oxidation vanadium can absorb infrared ray, produce tepid effect, raise indoor temperature thereby; Contrary, in torrid weather, in ultrathin layer mixture, the element of two kinds of material that agglutinate is together produces corresponding change, reflex infrared ray, make indoor temperature cool thereby. Layer mixed the tungsten of content of the 2 ％ in material to decide 2 oxidation vanadium is absorption of heat still come loose hot.
It is reported, glass of this kind of intelligence after 5 years will appear on the market, and its price compares tower above of existing and common glass only 20 ％ .
