Starting from
common graphite powder, graphene coating was deposited onto
copper plate via electrophoretic deposition (EPD) method. The
deoxygenation of carbon was confirmed by bathochromic
shifting in UV spectroscopy. Graphene protection layer was
further characterized electrochemically via potentiodynamic
polarization testing in chloride solution. Potentiodynamic
polarization curves show the decrease of both corrosion
potential (Ecorr) and corrosion current (icorr), suggesting
graphene protection layer decreases the copper dissolution
process..
