Abstract
A flexible conductive film, which relates to a conductive film, comprises two layers of flexible transparent films, two graphene conductive layers are arranged between the two layers of flexible transparent films, transparent insulating points are arranged between the two graphene conductive layers, and the flexible conductive film can be used in the production of resistive touch screens. Since the invention adopts graphene to replace ITO (indium tin oxide) as the material of the conductive film and the transparent insulating points are arranged between the two graphene conductive layers, when no pressure is applied, the two graphene conductive layers are separated from each other under the support of the transparent insulating points; after pressure is applied, the two graphene conductive layers are in contact with each other to conduct at the position where pressure is applied, so that an electric signal is generated; and the touched position is detected by a control circuit, so that touch operation is conducted. The touch screen made of graphene has the advantages of sensitive touch response, high light transmittance, high conductivity, low cost and environment-friendliness.
