We report the deposition of films composed overlapped and stacked platelets graphene oxide (G-O) reduced by an electrophoretic (EPD) process. The oxygen functional groups G-O were significantly removed EPD process, as-deposited film showed improved electrical conductivity (1.43 × 104 S·m−1) over papers made filtration method (0.53 10−3 S·m−1). This for reducing without added agents has potential high-yield, large-area, low-cost, environmentally friendly production platelets.
