As a novel two-dimensional laminar carbon nano material

graphene has excellent mechanical strength

high electron mobility

coefficient of thermal conductivity and unique chemical structure. Graphene can impart polyurethane (PU) with better mechanical

electrical

thermal and electromagnetic shielding properties as a filler

which make it a hotspot in composite material research field in recent years. In this paper

the research progress of modified graphene and incorporating graphene into polyurethane material was reviewed. The preparation method and performance of PU composites were classified and the common model establishing method on tensile

compression

thermal conductivity was analyzed. Furthermore

the challenge and opportunity of bulk production for graphene/polyurethane composites were prospected.
