美国赖斯大学研究人员利用市面上普通的纳米炭黑粒子,结合多孔聚合物研制出一层特殊材料,放置在滤膜表面。这层材料能吸收80%的阳光能量,只通过太阳能就可以加热海水、产生水蒸气。添加了特殊材料层的滤膜厚约几毫米。研究人员说,如果用聚光手段,每平方米滤膜每 Rice researchers at the University of the United States using the common nano-carbon black particles on the market, combined with the porous polymer developed a special material placed on the filter surface. This layer of material can absorb 80% of the sun’s energy, only solar energy can heat the sea water to produce water vapor. The filter with the special material layer is a few millimeters thick. The researchers said that if the means of concentration, per square meter filter per
