题目What is unique about chemically converted graphene?

时间201494星期四上午930

地点:909号楼一楼B会议室(Conference Room B, 909-1F)

 

摘要:

From a chemistry/materials point of view, graphene is a giant conductive polymer. Chemically modified graphene can be prepared in large quantity by chemical conversion of natural graphite through the well-known graphite oxide. Compared with pristine graphene, chemically converted graphene (CCG) or reduced graphene oxide has very unique chemical and physical properties. In this talk, I will highlight a few of these properties and particularly demonstrate how we can take advantage of the unique chemical molecular structure of CCG and supramolecular interactions to synthesize two classes of unprecedented graphene-based soft materials: the densest yet highly porous carbon gel film and the ultralight yet super-elastic conductive aerogel. I will also show how these unique graphene gels can lead to record-high-energy density supercapacitors, new generation of separation membranes and enable the successful synthesis of mechanically robust, stimuli-responsive and electroconductive polymer hydrogels that are unattainable with the traditional techniques.
