style="text-indent:2em;">幸运快三代理 ?010年石墨烯获得诺贝尔物理学奖以来,科学家和产业界对石墨烯就开始狂热的追逐。在追逐石墨烯的同时,一大批类石墨烯的二维材料也被相继发现,如何对其准确定义事关相关材料产业的发展。记?7日从泰州巨纳新能源有限公司获悉,该公司牵头起草的我国首个石墨烯国家标准GB/T 30544.13-2018:《纳米科技 术语 ?3部分:石墨烯及相关二维材料》正式发布。该标准也是二维材料领域的第一个国家标准?</p> <p style="text-indent:2em;"> 类石墨烯的二维材料家族涉及学科跨度大、范畴广、种类多,一直以来呈现多点开花、新现象、新应用频出的创新态势。二维材料是当下最前沿的科研应用领域之一,涵盖了印刷电子、柔性电子、超级电容、太阳能电池、量子点、传感器、半导体制造等,具有十分优异的机械、热学、光学特性,是多领域实现颠覆式创新的基础?</p> <p style="text-indent:2em;"> 根据国家标准的定义,由一层或几层构成,其中每一层内的原子与所在层内的邻近原子紧密成键结合,有一个维度(即其厚度)处于纳米或更小尺度,其余两个维度通常处于更大尺度的材料,称为二维材料?</p> <p style="text-indent:2em;"> 二维材料究竟有什么优异性能?由于单层二维材料的表面原子几乎完全裸露,相比于体相材料,原子利用率大大提高。通过厚度控制和元素掺杂,就可以更加容易地调控能带结构和电学特性。因此,二维材料更利于化学修饰,也更利于电子传递,同时它的柔性和透明度高,在可穿戴智能器件、柔性储能器件等领域前景诱人?</p> <p style="text-indent:2em;">幸运快三代理 我国首个石墨烯和二维材料国家标准主要由泰州巨纳新能源有限公司、东南大学等单位起草,前者于2010年成立,是国内最早从事石墨烯研究、检测、应用、标准化工作的公司之一?</p> <p style="text-indent:2em;"> <br /> </p></div><div id="rpt7hb9qi553h" class="meneame"><span class="disabled"><
