In response to carbon dioxide emission regulations, an internal combustion engine vehicle using a fossil fuel is being converted into an eco-friendly vehicle. Hydrogen electric vehicles are attracting attention as a next-generation transportation for using electricity produced from hydrogen fuel. The liner, which is one of the tank components, prevents the internal hydrogen gas from leaking to the outside. When a metal liner is replaced with a polymer liner, it is possible to improve the fuel efficiency of the hydrogen electric vehicle by reducing the weight of the hydrogen storage tank. In this study, a barrier coating composed of polyvinyl alcohol (PVA)/graphene oxide (GO) was applied to the liner material to compensate for the disadvantages of polymer liners, which have lower gas barrier properties compared to metal liners. Validation of the excellent gas barrier properties through oxygen transmission rate(OTR) and chemical analysis through FT-IR, Raman, and XRD were conducted. |
