NOVELTY - Preparation of graphene/nanosilver/feather composite material comprises adding 0.01-100 g/L silver nitrate solution with 0.01-100 g/L graphene oxide aqueous solution, mixing by stirring uniformly, where mass ratio of silver nitrate and graphene oxide is 1:1-1:10, slowly adding bird's nest, ultrasonically processing, putting in a reaction kettle at 160-220 degrees C for 30-600 minutes, taking out, repeatedly washing with ethanol, centrifuging and drying to obtain graphene/nanosilver/feather composite material, redispersing in deionized water to prepare 0.01-10 mass% graphene/nanosilver colloidal solution, sucking into a disposable syringe, slowly injecting into feather shaft until cavity is full, drying at room temperature for 24 hours, obtaining feather material, immersing in 0.01-10 mass% graphene/nanosilver colloidal solution, slowly adding glutaraldehyde, uniformly stirring for 30-300 minutes, repeatedly washing with deionized water and ethanol, and naturally drying. USE - Preparation of graphene/nanosilver/feather composite material (claimed). ADVANTAGE - The method uses graphene/nanosilver composite material to modify the feather, imparting the feather with good conductivity, antibacterial, thermal and mechanical properties.
