Graphene shows great potential applications in functional coating, electrodes, and ultrasensitive sensors, but highyield and scalable preparation of fewlayer graphene (FLG) by mechanical exfoliation method is still a formidable challenge. In this work, a novel twostep method for highyield preparation of FLG is developed by combining resonance ball milling and hydrothermal treatment.
Continuous mechanical exfoliation of graphene sheets via threeroll mill J. Chen et al. Electronic supporting information: Poly Vinyl Chloride (PVC, ) and Dioctyl phthalate (DOP, 50ml) were used to prepare an adhesive. Then added the adhesive to the feed and centre rolls of the threeroll mill.
Dispersion and exfoliation both occur in the adhesive, and while the threeroll mill machine is used widely in the rubber industry, meaning it is freely available for industrial production, it does make procuring pure graphene a challenge, as it leaves behind PVC and DOP. Figure 2.
