Researchers from KTH Royal Institute of Technology, University of New South Wales and University of Milan have a reported a reproducible and scalable method for producing graphene oxide (GO) nanosheets from commercial carbon fibers. The process involves exfoliating carbon fibers with nitric acid, which reportedly provides high yields of one-atom-thick sheets of graphene oxide with characteristics comparable to commercial GO sourced from mined graphite.

The team explained that the proof of concept was carried out with carbon fibers derived from polyacrylonitrile (PAN), a widely available polymer that undergoes high-temperature oxidation and graphitization. The method could be duplicated with other raw sources, such as raw sources such as biomass or forest industry sidestreams.
