A highly effective flame retardant (FR) nanocoating system was developed by conducting polymerization of dopamine within a liquid crystalline graphene oxide (GOLC) scaffold. The LC feature of GO enables to produce uniform coatings on multiple types of surfaces, including silicon wafer and flexible polyurethane (PU) foam that indicates this coating is potentially universal. An aqueous LC facilitates fast diffusion of dopamine within the GO scaffold where it undergoes polymerization into polydopamine (PDA). PDA/GO exhibited a highly efficient FR performance of PU foam, which can be attributed to the synergistic interplay afforded by its anti-oxidative and intumescent char formation functions of PDA/GO. This nanocoating does not substantially influence the mechanical properties of PU foam, and exhibited significantly enhanced water stability promoted by the adhesive character of PDA and the hydrophobic reduced GO form by PDA.
