▎ 摘 要
NOVELTY - Preparation of nanoparticles-coated graphene sheet involves suspending silver target in aqueous solution of colloidal graphene oxide, stirring constantly with a magnetic stirrer, irradiating using laser beam, and regulating laser power for changing density and size of silver nanoparticles. USE - Preparation of nanoparticles-coated graphene sheet (claimed). ADVANTAGE - The method efficiently and economically provides nanoparticles-coated graphene sheet by simple process without using special equipment and without causing pollution to the environment.
