石墨烯的抗拉强度达到了130 GigaPascals，是铁的200倍。但研究人员试图将石墨烯加入到金属复合材料中的尝试一直未能取得成功。现在，韩国先进科学技术研究院的研究人员宣布他们首次成功在金属铜和镍中结合石墨烯，新复合材料的强度达到了铜的500倍和镍的180倍。这是一项重大突破，研究报告发表在《Nature Communications》上。他们是利用化学气相沉积法在金属沉积基底上生成一层石墨烯，然后再沉积一层金属，重复这一过程，创造出多层金属-石墨烯复合材料。石墨烯的质量仅仅占0.00004%，但强度却增加了数百倍。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
