[0020] The preparation method of the low-resistance and low-additive conductive film of the present invention is specifically implemented according to the following steps:
[0021] Step 1. Add AgNO 3 3-7 parts (parts by mass), 5-9 parts (parts by mass) of polyvinylpyrrolidone, and a concentration of 5×10 -3 mol / LFeCl 3 500-800 parts (mass parts) of ethylene glycol solution, stirred and dissolved at 70°C for 40-50 minutes, and reacted at 140-160°C for 80-100 minutes, cooled, washed with acetone, washed with deionized water, and centrifuged Get nano silver wire;
[0022] The diameter of the obtained nano silver is 70-120 nm, the length is 20-40 μm, the aspect ratio is 170-570, and the amount of granular nano silver is extremely small.
[0023] Step 2: 20-30 parts (mass parts) of silver nanowires, 10-20 parts (mass parts) of cellulose nanocrystals, 50-70 parts (mass parts) of dimethacrylic acid polyol / ether and acrylic acid Butyl ester (the mass ratio of bismethacrylic acid polyol / ethe...
Example Embodiment
[0025] Example 1
[0026] (1) Add 0.5g AgNO 3 , 0.7g polyvinylpyrrolidone (PVP) and a concentration of 5×10 -3 mol / LFeCl 3 70ml of ethylene glycol solution, stirred and dissolved at 70°C for 40min, then heated to 160°C for constant temperature reaction for 80min, naturally cooled to room temperature, the obtained product was washed with acetone to remove PVP, and then washed with deionized water and centrifuged. , Get nano silver wire;
[0027] The diameter is between 60 nm and 110 nm, the length is between 20 μm and 40 μm, the aspect ratio is between 180 and 500, and the amount of granular nano silver is quite small.
[0028] (2) 15 parts of silver nanowires, 20 parts of cellulose nanocrystals, 63 parts of polyethylene glycol 200 dimethacrylic acid and butyl acrylate (the mass ratio of polyethylene glycol 200 dimethacrylic acid to butyl acrylate is 1:3) Mix uniformly, and seal in a mold after dewatering and deoxygenating with nitrogen, adding 2 parts of azobisisobutyronitrile (AIBN...

[0029] Example 2
[0030] (1) 0.3g AgNO 3 , 0.4g polyvinylpyrrolidone (PVP) and a concentration of 5×10 -3 mol / LFeCl 3 60ml of ethylene glycol solution was stirred and dissolved at 70°C for 45min, then heated to 140°C for constant temperature reaction for 90min, and naturally cooled to room temperature. The obtained product was first washed with acetone to remove PVP, and then fully washed with deionized water and centrifuged. Get nano silver wire;
[0031] Its diameter is between 70-120nm, the length is between 20-30μm, the aspect ratio is 170-300, and the amount of granular nano silver is quite small.
[0032] (2) 20 parts of silver nanowires, 10 parts of cellulose nanocrystals, 68 parts of polyethylene glycol 500 dimethacrylic acid and butyl acrylate (the mass ratio of polyethylene glycol 500 dimethacrylic acid to butyl acrylate is 1:2) Mix uniformly, and seal in a mold after purging nitrogen to remove water and oxygen. Add 2 parts of azobisisobutyronitrile (AIBN) at 70°C for cat...
