摘　　要：A method was developed and proposed to fabricate graphene-enhanced hollow microlattice materials,which include the three-dimensional(3D)printing,nanocomposite electroless plating,and polymer etching technologies.The surface morphology and uniformity of as-deposited coatings were systematically characterized and analyzed.Moreover,the mechanical properties of the microlattices were investigated through quasi-static compression tests.The results demonstrated that a uniform Nickel-phossphorous-graphene(Ni-P-G)coating was obtained successfully,and the specific modulus and strength were increased by adding graphene into the microlattice materials.The optimal mass concentration of graphene nanoplatelets was obtained after comparing the specific modulus and strength of the materials with different densities of graphene,and the strength mechanism was discussed.
