Abstract
In this paper, an electrochemical method was proposed to recycle nanoarchitectonics of
graphene oxide (GO) from carbon fiber reinforced polymer (CFRP). In the recycling process, NaCl
solution with varied concentrations (3% and 10%) and tap water were used as electrolyte, while the
impressed current density varied from 2.67 A/m2 to 20.63 A/m2. The results indicated that in NaCl
electrolyte, the obtained nanoarchitectonics of GO contained a large amount of nano-carbon onions
(NCO) produced by etching CFRP, while high purity GO was produced when tap water was used as
electrolyte. The higher current density improved the production efficiency and resulted in a finer
GO particle size. The proposed recycling method of GO is economical and simple to operate. It also
provides an alternate approach to handle discarded CFRP.
