    In this work, the waterborne graphene oxide/polyurethane-acrylate (GO-WPUA) oligomer was prepared based on isophorone diisocyanate (IPDI), polyether polyol (NJ-220), graphene oxide (GO), dimethylol propionic acid (DMPA) and hydroxyethyl methylacrylate (HEMA). A series of the UV-curable waterborne graphene oxide/polyurethane-acrylate composites containing different content of GO were obtained with oligomer, monomers (BA and TPGDA) and photoinitiator Darocur 1173. The structure, viscosity, particle size and surface tension of emulsions were measured. Some mechanical performances, solvent resistance, the water absorption and thermal property of films were investigated. When the content of GO is 0.01%, the UV-curable film has the best mechanical property. The obtained composites have great potential application such as coatings, leather finishing, adhesives, sealants, plastic coatings and wood finishes.
