Synthesis of high-performance protective coatings with multifunctional properties is important for many applications across industry sectors, civil engineering and environmental protection.In this regard, graphene has emerged as a the most promising material due to its many superior properties that has not been distinguished in a single material before. In this presentation we will overview our progress on synthesis of multifunctional graphene composite with enhanced mechanical, barrier, fire retardant and antibacterial properties.These composites are created from single layers of graphene or graphene oxide nanosheets that are assembled in layered composite structures composed with other additives to achieve targeting properties.  The mechanical study showed that prepared graphene composite films have a high degree of adhesion (ASTM-class 4B) and robustness when coated on metal and glass substrates. The characterization of their antibacterial performance significantly outperforms GO and rGO films showing the reduction of bacterial colonization up to 99.92 %.  Finally, the flame retardant performance of these composites was demonstrated by treating different surfaces making them to be non-flammable. The exceptional multifunctional properties of this graphene based composite offers a great potential for industrial, structural, environmental, and biomedical coating applications.
