Preparation and Properties of Graphene Oxide-Modified Waterborne Polyurethane-Acrylate Hybrids

A series of graphene oxide-modified waterborne polyurethane-acrylate (GEO/WPUA) hybrids were prepared and characterized by FT-IR, SEM, TEM and XRD. The result shows that graphene oxide in the hybrid has good dispersion. The mechanical property, thermal stability and water resistance of hybrids with different content of GEO were investigated. The results indicate that GEO/WPUA films have bigger tensile strength and hardness than pure WPUA. When the content of GEO is 0.015%, the hybrid has the best water resistance. The obtained GEO/WPUA hybrids have great potential application such as coatings, leather finishing, adhesives, sealants, plastic coatings and wood finishes.
