[0030] On the other hand, the embodiment of the present invention also provides a method for preparing the above-mentioned flexible transparent electrode. The process of the preparation method is as follows image 3 shown, see also Flexible Transparent Electrode figure 1 , including the following steps:
[0031] S01. Attach silver nanowires on one side of the filter membrane: filter the dispersion of silver nanowires 21 with filter membrane 3, so that the silver nanowires 21 are attached to one surface of the filter membrane;
[0032] S02. Lay the plant leaf veins, the filter membrane with silver nanowires, and the flexible base in sequence: stick the filter membrane 3 on the surface of the flexible base 1, and make the filter membrane with the silver nanowires 21 The surface of the membrane 3 is attached to the surface of the flexible substrate 1, and then the prepared plant veins 4 from which the mesophyll has been removed are stacked on the other surface of the filter mem...
Embodiment 1
[0052] The invention provides a kind of flexible transparent electrode, its structure is as follows figure 1 As shown, a PET flexible substrate 1 is included, and a metal conductor layer 2 is bonded on the surface of the flexible substrate 1 . Wherein, the metal conductor layer 2 has a vein-like pattern of an osmanthus leaf plant, and the metal conductor is a silver nanowire with a diameter of 50 nm and a length of 2 cm.
[0053] Its preparation method is as follows, refer to image 3 Described technological process:
[0054] Step S11: Take 3ml of the silver nanowire dispersion and pour it twice into a vacuum filtration device with a fibrous filter membrane placed at the mouth of the bottle, so that the silver nanowires are attached to one surface of the filter membrane;
[0055] Wherein, the preparation method of the silver nanowire dispersion liquid: take the very large silver nanowire (diameter 50nm, length 2cm, such as figure 2 As shown) 1 mg, dissolved in 50 ml of abs...
Embodiment 2
[0062] The invention provides a kind of flexible transparent electrode, its structure is as follows figure 1 As shown, a PET flexible substrate 1 is included, and a metal conductor layer 2 is bonded on the surface of the flexible substrate 1 . Wherein, the metal conductor layer 2 has a poplar plant leaf vein pattern, and the metal conductor is a silver nanowire with a diameter of 20 nm and a length of 200 μm.
[0063] Its preparation method is as follows, refer to image 3 Described technological process:
[0064] Step S21: Referring to step 11 in Example 1, the difference is that the silver nanowire has a diameter of 20 nm and a length of 200 μm;
[0065] Step S22: refer to step 12 in Example 1;
[0066] Step S23: refer to step 13 in Example 1;
[0067] Step S24: Refer to step 14 in Embodiment 1.
