▎ 摘　　要

NOVELTY - The preparation method of self-assembled graphene inline growth nano-rod array composite film involves immersing metal zinc sheet in a graphene oxide solution, leaving still the mixture, reacting at room temperature, removing, and drying to obtain zinc sheet self-assembled reduced graphene film, grafting the graphene film directly from the zinc sheet to obtain a self-assembled graphene film, adding self-assembled graphene film to nano-rod array growth solution, and hydrothermally reacting. USE - Preparation of self-assembled graphene inline growth nano-rod array composite film (claimed). ADVANTAGE - The method enables the preparation of self-assembled graphene inline growth nano-rod array composite film with excellent mechanical property and photocatalytic property.
