Optically consistent transparent conductive film and preparation method thereof

An optically consistent transparent conductive film, wherein the optically consistent transparent conductive film comprises a substrate, an optically consistent conductive layer and a protective layer;

• wherein the substrate comprises a rigid or/and flexible substrate;
• the optically consistent conductive layer comprises a conductive area, the conductive area comprises metal nanowires A and nanoparticles B, the metal nanowires A superimpose or crosslink to form a network in a conductive area, the nanoparticles B function to weld the metal nanowires A;
• the nanoparticles B are uniformly distributed in the conductive area, the influence of the nanoparticles B on the conductivity of the metal nanowires A is less than 50%;
• the optically consistent conductive layer comprises a non-conductive area obtained by etching the metal nanowires A in the conductive area, the non-conductive area comprises uniformly distributed nanoparticles B, the nanoparticles B do not form a continuous conductive pathway with each other in the non-conductive area;
• the vaporization temperature of the nanoparticles B is higher than that of the metal nanowires A;
• the corrosion rate of the metal nanowires A is faster than nanoparticles B;
