▎ 摘　　要

NOVELTY - Preparation of silver nanoparticles-carbon nanotubes-embedded graphene oxide composite film involves preparing aqueous dispersion (A) containing 1 part mass cetyltrimethylammonium bromide-functionalized silver nanoparticles, preparing aqueous dispersion (B) containing 4-5 parts mass oxidized graphene, mixing dispersions (A) and (B), adding 1 part mass polydiallyldimethylammonium chloride functionalized carbon nanotubes, filtering in vacuum suction filter using a filter paper and drying. USE - Preparation of silver nanoparticles-carbon nanotubes-embedded graphene oxide composite film used for detecting antibiotic residue in water environment (claimed). ADVANTAGE - The method efficiently provides silver nanoparticles-carbon nanotubes-embedded graphene oxide composite film which rapidly detects antibiotic residue in water environment.
