日前,南开大学化学学院陈永胜教授团队在碳纳米材料方面研究获得重要进展,首次获得了一种同时具有泊松比为零和有优异弹性的材料。介绍该成果的论文发表于最新一期学术刊物《自然-通讯》。这种“神奇”的黑色材料,看起来就像黑色棉花或海绵一样,其密度可比空气还轻,能反复压缩,具有非常好的弹性。科研 Recently, the team of Professor Chen Yongsheng of Nankai University Chemistry College made important progress in the research of carbon nanomaterials. For the first time, a material with both Poisson’s ratio of zero and excellent elasticity was obtained. Papers describing the results are published in the latest issue of the journal Nature - Communications. This “magical” black material looks like black cotton or sponge, its density is lighter than air, can be repeatedly compressed, has very good elasticity. research
