▎ 摘　　要

NOVELTY - The preparation method of graphene film involves using roll-to-roll printing technique to fabricate uniform controlled thickness on flexible substrate under controlled conditions, based on different viscosities and different concentrations of water-based and oily graphene ink materials. The substrate is flexible substrate such as polyethylene terephthalate, polyethylene naphthalate or polyimide. USE - Preparation of graphene film used for flexible optoelectronic device and photovoltaic device. (claimed). ADVANTAGE - The method enables preparation of graphene film with increased flexibility and controlled conductivity by simple and economical process.
