To improve the corrosion resistance of waterborne polyurethane-acrylate coating,a series of water-polyurethane-acrylate / graphene oxide( WPUA / GO) hybrid emulsions were prepared through in-situ polymerization. X-ray diffraction,Raman spectroscopy,and infrared spectroscopy were utilized to characterize the structure and morphology of graphene oxide. The microstructure of WPUA / GO hybrid emulsion was observed by transmission electron microscopy,and scanning electron microscopy. The anti-corrosion propertie...
