USE - The flexible transparent conductive film is useful in biocompatible photoelectric device and wearable device. ADVANTAGE - The flexible transparent conductive film: has excellent conductivity, excellent adhesion and biocompatibility. DETAILED DESCRIPTION - Preparing silver nanowire/graphene based silk-based flexible transparent conductive film, comprises (i) preparing 1-10 g/l silver nanowires aqueous solution, adding 1-10 g/l terminal amino hyperbranched polymer or terminal hydroxy hyperbranched polymer aqueous solution, reacting at room temperature for 24 hours, washing repeatedly with deionized water and ethanol, and drying to obtain terminal amino hyperbranched polymer-modified silver nanowires or terminal hydroxy hyperbranched polymer modified silver nanowires, (ii) washing silicon chip with ethanol and acetone, carrying out ultrasonic washing in water for 20 minutes, drying the surface of the silicon chip using nitrogen gas, immersing the silicon chip in 5% silane coupling agent KH-550 aqueous solution at room temperature for 24 hours, where the bath ratio is 1:50, then washing, and vacuum drying, (iii) preparing terminal amino-terminated hyperbranched polymer modified silver nanowires and hydroxy-terminated hyperbranched polymer modified silver nanowires into 0.1-10 g/l aqueous solution, spin-coating the amino-terminated hyperbranched polymer-modified silver nanowires, hydroxy-terminated hyperbranched polymer-modified silver nanowires, and amino-terminated hyperbranched polymer-modified silver nanowires onto the surface of the silicon chip, silver nanowire-graphene oxide was spin-coated on the surface of the silicon chip, repeating the above operations, determining the silicon surface of the silver nanowires-graphene oxide coating layer, and (iv) immersing silver nanowire-graphene oxide film in a hydroiodic acid solution for reduction to obtain a silver nanowire-graphene film, then slowly dropping silk fibroin solution onto the surface of the silver nanowire-graphene film, and air-drying gently stripping from the surface of the silicon chip to obtain final product. An INDEPENDENT CLAIM is also included for silver nanowire/graphene based silk-based flexible transparent conductive film obtained by above method.
