Abstract

We synthesized waterborne polyurethane (WPU)/allyl isocyanate modified graphene oxide (iGO) nanocomposites by UV curing, and the effects of iGO on the mechanical, dynamic mechanical, and thermal properties of the nanocomposites were systematically investigated. It was shown that the iGO chemically incorporated into the WPU chains by covalent bonding acts as a multifunctional cross-linking agent as well as reinforcing filler. Consequently, the tensile strength, glassy and rubbery state moduli, glass transition temperature, and thermal stability of the WPU were significantly increased up to an iGO content of 1%, beyond which most of the above properties showed a decrease, due probably to the auto-inhibition of the allyl compounds.
