Delamination of polymer films over the course of time is inevitable but with multilayering technique, a fresh layer ensures longevity of the material's functions. This project aims to fabricate multilayered graphene or graphene oxide (GO) � polymer films for multifunctional coatings and devices. GO film was deposited through Langmuir-Blodgett (LB) method on poly(ethylene terephthalate) (PET) substrate and its antibacterial activity was evaluated. Results reveal that GO is surface active at air-water interface by displaying a classic ?-area isotherm. The GO films exhibit antibacterial efficacy that is layer dependent. Compared to spin-cast GO, the films deposited through LB show more stability and retained antibacterial activity even after agitation by ultrasonication. Three layers of GO display roughly 97% transparency. These findings serve as baseline information towards the application of multilayered GO-polymer nanocomposites.
