The invention provides a graphene-reinforced waterborne polyurethane high-barrier material and a condom. The high-barrier material adopts the modified graphene oxide to improve the compatibility with polyurethane materials, increases the interaction between the graphene and polyurethane molecular chains, and achieves the purpose of improving the mechanical property and the barrier property of polyurethane; and simultaneously, introducing carbon-carbon double bonds at the tail end of a polyurethane molecular chain, and bonding the carbon-carbon double bonds with the carbon-carbon double bonds on the natural latex molecular chain through free radical reaction, so that the fusion of the interface between the natural latex layer and the graphene/waterborne polyurethane interlayer is realized. The material can be used for manufacturing the graphene/polyurethane/natural latex composite structure condom with good barrier property and low cost. |
