Poly(dopamine)-treated graphene oxide/poly(vinyl alcohol) (dG-0/PVA) composite films were made and characterized. G-0 was modified with poly(dopamine) in aqueous solution and then chemically reduced to yield poly(dopamine)-treated reduced G-0. A combination of hydrogen bonding, strong adhesion of poly(dopamine) at the interface of PVA and G-0 sheets, and reinforcement by G-0 resulted in increases in tensile modulus, ultimate tensile strength, and strain-to-failure by 39, 100, and 89%, respectively, at 0.5 wt % dG-0 loading of the PVA. The dG-0 serves as a moisture barrier for water-soluble PVA, and the dG-0/PVA composite films were shown to be effective humidity sensors over the relative humidity range 40-100%.
