[交流] 日本人制作的100米连续石墨烯 100米!已有13人参与

Production of a 100-m-long high-quality graphene transparent conductive
film by roll-to-roll chemical vapor deposition and transfer process

   在滚轴带动的铜箔传送带上,用低压CVD方法制备连续的石墨烯,并用roll-to-roll方法进行转移;得到PMMA上100米长石墨烯带.
   本人拙见认为其亮点是--真的把这系统做出来了(我等只能想象),但是其中的关键技术,比如调节冷却速度,气流速度,铜箔带速等,以降低缺陷率,提高覆盖率,等提高graphene 的质量方面有待摸索和提高.
   一言以蔽之，就是把之前的技术进行了整合，并实现了自动化，但整合细节有待改进。
   但是那是整整100米啊亲,赶紧下下来看看吧.
摘要:A high-quality graphene transparent conductive film was fabricated by roll-to-roll chemical vapor deposition (CVD) synthesis on a suspended copper foil and subsequent transfer. While the high temperature required for the CVD synthesis of high-quality graphene has prevented efficient roll-to-roll production thus far, we used selective Joule heating of the copper foil to achieve this. Low pressure thermal CVD synthesis and a direct roll-to-roll transfer process using photocurable epoxy resin allowed us to fabricate a 100-m-long graphene transparent conductive film with a sheet resistance as low as 150 X /sq, which is comparable to that of state-of-the-art CVD-grown graphene films.
不知道有重复没.
