    Abstract
    Graphene oxide/TiO₂ (GO/TiO₂) thin films works as self-cleaning device have been developed in various method onto selected substrates. It was noticeable that graphene oxide is the best form in the group of graphene family. Under self-cleaning application, the wettability test and electroconductivity of the sample was the main characteristic for self-coating study. As planned, by addition of graphene to TiO₂ films produce a highly conductivity, transparent and produced promising enhanced photocatalytic activities. Moreover, superhydrophilic properties of GO/TiO₂ film surface film exhibits more as compared to TiO₂ film only within a short period of time. Thus under this finding, the photocatalytic activity of GO/TiO₂ films will be enhance as a result of improve charge separation efficiency because of the electron injection to graphene from TiO₂ conduction band. Other factor that contribute to self-cleaning activity is the electrical conductivity of the graphene added to TiO₂ thin film. The graphene added to TiO₂ films have a lot of potential in various indoor application due to its fantastic characteristics such as not expensive, transparent, highly conductive, exhibits superhydrophilic properties, and very much photocatalytically active.
