  Due to the desirable properties of poly xanthones, the present research investigates curing, thermal degradation and anticorrosion behavior of epoxy resin with poly(xanthone-amide) (PXAO) as curing agent, with melamine-functionalized Fe3O4 (m-Fe3O4) nanoparticles. Curing kinetics of the systems were dynamically studied using differential scanning calorimetry (DSC). Kinetic parameters including activation energy (Ea) and rate constant (K) were calculated using Kissinger’s method and Ozawa-Flynn-Wall equation. Mass reduction behavior (including mass reduction temperatures and Ea) and thermal stability were characterized using thermogravimetric analysis (TGA). The results indicated higher activation energy and residual degradation (from 35% to 43%) at 750℃ in nitrogen atmosphere in the systems containing nanoparticles, as compared to the systems without the m-Fe3O4 nanoparticles. Results of potentiodynamic polarization tests to evaluate corrosion performance of the resin epoxy-coated stainless steel, showed that the PXAO had improved the anticorrosion activity of epoxy resin. Moreover, introduction of the m-Fe3O4 nanoparticles to the curing mixture significantly increased anticorrosion behavior of the epoxy resin by enhancing the paths through which water and oxygen could diffuse.
