Embodiment 1
[0029] A preparation method of silver nanowire transparent conductive film is as follows:
[0030] (1) Add 1.11 g of polyvinylpyrrolidone and 0.03 g of NaCl to the polyol solution of 0.85 g of silver nitrate, mix and stir for 10 minutes to obtain a mixed solution; the polyol is ethylene glycol, and the volume is 0.05 L;
[0031] (2) Pour the mixed solution of step (1) into the reactor, react at 160 DEG C for 7h, and wash and stand for 3-4 times with deionized water to obtain silver nanowires; the prepared silver nanowires have better aspect ratio. The prepared silver nanowires have a diameter of about 100nm and a length of 30-50um.
[0032] (3) The dehydrated ethanol dispersion liquid that concentration is 0.1mol / l silver nanowire is added dropwise on the glass substrate and is 500r / min spin coating through 10s rotating speed; Then the glass substrate that spin is coated with silver nanowire is placed On a heating plate at 100°C for 10s to volatilize absolute ethanol; then d...
Embodiment 2
[0037] It is basically the same as in Example 1, except that the spin coating speed of the silver nanowire dispersion in absolute ethanol is 1000 r / min.
Embodiment 3
[0039] It is basically the same as in Example 1, except that the spin-coating speed of the silver nanowire dispersion in absolute ethanol is 2000 r / min.
