Amino-functionalization of graphene sheets and the fabrication of their nanocomposites
(1987–1994)Polymer Composites 31 #12 (2010)
Hu et of Fudan University, China functionalized expandagel graphitic oxide sheets by sequential thermal expansion, oxidation, acylation, and amidation.  Three types of amino-functionalized graphenes (a-Gphs) were prepared by exfoliating amino functionalized EGOs(a-EGO) through controlled ultrasonication..  Single layered graphene (0.43 nm) was achieved after ultrasonicating at 500 W for 20 min.  Functionalization improved thermal properties.(RDC 11/18/2010)
