The discovery published online in the journal Science was made by post-doctoral associates and undergraduate students and is a \u201cmajor advance in the field\u201d said Manish Chhowalla, professor and associate chair in the Department of Materials Science and Engineering in Rutgers\u2019 School of Engineering.<\/p>\n
This simple microwave treatment leads to exceptionally high quality graphene with properties approaching those in pristine graphene.<\/p><\/blockquote>\n
Having undergraduates as co-authors of a Science paper is rare but he said \u201cthe Rutgers Materials Science and Engineering Department and the School of Engineering at Rutgers cultivate a culture of curiosity driven research in students with fresh ideas who are not afraid to try something new.\u2019\u2019<\/p>\n
Graphene, which comes from graphite, a carbon-based material is 100 times stronger than steel and conducts electricity better than copper rapidly dissipating and heat, making it useful for many applications. Large-scale production of graphene is necessary for applications such as printable electronics, electrodes for batteries and catalysts for fuel cells.<\/p>\n
The easiest way to make large quantities of graphene is to exfoliate graphite into individual graphene sheets by using chemicals. The downside of this approach is that side reactions occur with oxygen \u2013 forming graphene oxide that is electrically non-conducting, which makes it less useful for products.<\/p>\n
Removing oxygen from graphene oxide to obtain high-quality graphene has been a major challenge over the past two decades for the scientific community working on graphene. Oxygen distorts the pristine atomic structure of graphene and degrades its properties.<\/p>\n
Chhowalla and his group members found that baking the exfoliated graphene oxide for just one-second in a 1,000-watt microwave oven, like those used in households across America, can eliminate virtually all of the oxygen from graphene oxide.<\/p>\n","protected":false},"excerpt":{"rendered":"
