[0038] The present invention also provides a method for preparing a flexible transparent conductive film, including: coating a first protective film layer and a second protective film layer on both sides of the use layer;
[0039] Wherein, the use layer is prepared according to the following method:
[0040] Coating the first UV hardening layer and the second UV hardening layer on both sides of the PET substrate, and coating the anti-blue light layer and the conductive layer on the second hardening layer in sequence;
[0041] The conductive layer is prepared according to the following method: with zinc acetate and Al(NO 3 ) 3 .9H 2 O is the raw material, and the conductive layer is obtained by liquid deposition and annealing. According to the present invention, in the present invention, the first protective film layer and the second protective film layer are respectively coated on both sides of the use layer; wherein, the materials used in the first protective film layer and the seco...

[0045] Example 1
[0046] 1) Preparation of use layer
[0047] Mix 100 parts by weight of solvent, 40 parts by weight of crosslinking monomer, 20 parts by weight of prepolymer, and 2 parts by weight of photoinitiator, and coat the mixture on a 23umPET substrate by gravure coating, oven The temperature is about 50-90 degrees, heated in an oven for 30-60 seconds, and then cured by ultraviolet light. The energy of the UV lamp is about 500-800mJ / cm 2 , A hardened layer with a thickness of 3μm, that is, a substrate coated with the first UV hardened layer and the second UV hardened layer; wherein the solvent is toluene; the crosslinking monomer is hexanediol diacrylate; the prepolymer is cyclic Oxygen acrylic resin; the photoinitiator is benzophenone and triethanolamine, and the mass ratio of benzophenone and triethanolamine is 2:1.
[0048] The anti-blue light layer is coated on the substrate coated with the UV hardening layer. Specifically, 60 parts by weight of viscous monomer, 5 parts...
