▎ 摘  要

Graphene oxide (GO) and polyethylenimine were successfully assembled into ultrathin films by using the electrostatic layer-by-layer self-assembly technique. The film assembling process was monitored by ultraviolet-visible spectroscopy. A linear increase in the film absorption with the number of deposited layers indicated that the (GO/PEI)(n) film depositions were uniform and reproducible. The photoelectrochemical properties of these multilayer films were investigated in an aqueous Na2SO4 solution, and it was found that the GO(PEI/GO)(2) film exhibited stable cathodic photocurrents.
