最近,美国科学家发明了一种超强纳米纸,它的基本成分是碳纳米颗粒。这种新型纸的硬度超过钢铁,然后它又的确像普通纸张一样柔软,它的韧性则比普通纸张大得多。 Recently, the United States scientists invented a super-nano paper, its basic component is carbon nanoparticles. This new type of paper is more rigid than steel and then it is really as soft as regular paper, and its toughness is much greater than regular paper.
