最近,日本工业技术院名古屋工业技术研究所开发成功了一种当达到一定温度(临界温度)以上,光的透过量即可自动地减少的窗玻璃用涂膜。据称,这是在二氧化钒内掺杂钨而制成的,其特点是通过改变钨的比率,可自由地设定临界温度。夏天具有控制太阳光侵入室内的效果,减轻空调冷气的负载;冬天则能防止空凋暖气的流失,可望作为一种节能材料付诸实用。 Recently, the Japan Industrial Technology Institute Nagoya Institute of Technology has successfully developed a coating that reaches a certain temperature (critical temperature) above, the amount of light transmitted can be automatically reduced window coating. Allegedly, this is made of tungsten dioxide doped vanadium dioxide, which is characterized by the ratio of tungsten can be freely set the critical temperature. Summer has the effect of controlling the intrusion of sunlight into the room and alleviating the load of air-conditioning and air-conditioning; in winter, it can prevent the loss of empty withered heat and is expected to be put into practical use as an energy-saving material.
