Claisen rearrangement of graphite oxide: a route to covalently functionalized graphenes.
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. The chemical modification of nano-or micro-molecular surfaces is widely used for the precise structural and/or electrical manipulation of bulk materials. [1] In particular, atomically thin graphitic molecules such as fullerene, carbon nanotubes, and graphene display pronounced ...
متن کاملPreparation and properties of electrically conductive PPS/expanded graphite nanocomposites
Nanocomposites based on poly (phenylene sulfide) (PPS) and expanded graphite (EG) or ultrasonicated EG (S-EG) were prepared by melt blending. Morphologies of the nanocomposites were examined using both SEM and TEM. Electrical conductivity and thermal stability of PPS were notably enhanced by the introduction of EG. The percolation threshold values are 1 wt% (S-EG) and 2 wt% (EG) for PPS/S-EG an...
متن کاملSonochemical preparation of functionalized graphenes.
A convenient sonochemical method is described for the preparation of polystyrene functionalized graphenes starting from graphite flakes and a reactive monomer, styrene. Ultrasonic irradiation of graphite in styrene results in the mechanochemical exfoliation of graphite flakes to single-layer and few-layer graphene sheets combined with functionalization of the graphene with polystyrene chains. T...
متن کاملRaman spectra of graphite oxide and functionalized graphene sheets.
We investigate Raman spectra of graphite oxide and functionalized graphene sheets with epoxy and hydroxyl groups and Stone-Wales and 5-8-5 defects by first-principles calculations to interpret our experimental results. Only the alternating pattern of single-double carbon bonds within the sp2 carbon ribbons provides a satisfactory explanation for the experimentally observed blue shift of the G b...
متن کاملAntimicrobial Bamboo Materials Functionalized with ZnO and Graphene Oxide Nanocomposites
Bamboo materials with improved antibacterial performance based on ZnO and graphene oxide (GO) were fabricated by vacuum impregnation and hydrothermal strategies. The Zn2+ ions and GO nanosheets were firstly infiltrated into the bamboo structure, followed by dehydration and crystallization upon hydrothermal treatment, leading to the formation of ZnO/GO nanocomposites anchored in the bulk bamboo....
