PREPARATION METHOD FOR GRAPHENE OXIDE SUITABLE FOR GRAPHENE PRODUCTION

摘要

Pristine graphene oxide, wherein pristine graphene oxide is defined in that it comprises at least 10 6 carbon atoms and if it is reduced using a reduction protocol in which graphene oxide is reduced by a 1/1 mixture of hydriodic acid 57 % and trifluoroacetic acid by placing the graphene oxide on a Si/SiO 2 substrate and exposing it to the vapour of the reduction mixture in a chamber for 5 minutes at room temperature and for another 10 minutes at 80° C, pristine graphene oxide yields graphene, and graphene is defined in that in the Raman spectrum of graphene the 2D peak is higher than or equal to the G peak, and moreover the full width of the 2D peak at half maximum (FWHM) is less than 38 cm -1 .
