  • Title: Photoelectrochemical properties of graphene oxide-based electrostatically self-assembled film.
    Author: Ye Z, Li BB, Peng J, Wang KZ.
    Journal: J Nanosci Nanotechnol; 2014 May; 14(5):3932-6. PubMed ID: 24734667.
    Abstract:
    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.
