▎ 摘  要

NOVELTY - Laser marking material comprises 100 pts. wt. polyamide and 0.1-5 pts. wt. continuous nano silver/graphene foam. USE - The laser marking material is useful in continuous nano silver/graphene foam blending polyamide (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing laser marking material comprising (i) dispersing silver-containing precursor, stabilizer and control agent in an organic solvent and sonicating to obtain silver-containing precursor dispersion, (ii) placing the graphene foam in the silver-containing precursor dispersion obtained in step (i), immersing the glass in a protective gas atmosphere for microwave treatment, filtering the filter cake, washing and drying the filter cake to obtain nanometer silver wire-graphene composite foam, (iii) blending and molding the nano-silver wire-graphene composite foam obtained in step (ii) with polyamide, and (iv) molding to obtain final product.
