Recent progress of preparation and properties of graphene/polyurethane nanocomposites
In recent years,graphene/polyurethane nanocomposites have attracted much attention due to their su-perior comprehensive properties.Incorporating graphene or its derivatives into PU matrix could significantly im-prove the physical mechanical,thermal,electromagnetic and other properties,which meets the special require-ments of high-performance and multi-functional polymer composites.In this paper,the functional modification methods of graphene nanosheets,including covalent modification and non-covalent modification were first intro-duced.Furthermore,the fabrication processes of graphene/polyurethane nanocomposites,including in-situ pol-ymerization,solution blending,melt blending,aqueous(latex)blending,etc.,were briefly introduced.The re-cent research progress of graphene/polyurethane composites in mechanical,electrical,dielectric,thermal,gas barrier,flame retardant,electromagnetic interference shielding and corrosion resistant properties were all re-viewed in detail.The future challenges and development prospects of high-performance graphene/polyurethane nanocomposites were also prospected.
