Solution-based Process Could Produce Tuned Graphene in Bulk

Researchers in Taiwan have developed a solution-based process for producing graphene that is tuned to exhibit specific electrical and mechanical properties . While solution-based exfoliation of graphene has been possible for some time, this new approach uses pulses of an electrical voltage rather than a constant voltage to produce the desired effects. The researchers believe that their work, which was reported in the journal Nanotechnology , could pave the way for new applications for graphene in drug delivery or electronics. Graphene production methods have been seen as an obstacle to the use of the material in a range of applications for which it has been targeted. The mechanical exfoliation of graphene sheets from graphite, while producing the best quality graphene for electronic applications, is decidedly un-scalable. And production methods that are more scalable lack ...
