Embodiment 1
[0108] see figure 2 , 3 As shown, single-layer graphene is used as a low-voltage transparent electrothermal film for heating components, and the electrodes are printed with silver paste.
[0109] The preparation process is as follows:
[0110] 1. Transfer a layer of graphene on PET (transparent substrate) with a thickness of 125 μm. The graphene has been doped and the square resistance is 250Ω / □;
[0111] 2. Use screen printing equipment to print the silver paste electrode pattern on the transferred graphene, the shape of the pattern is as follows: figure 2 As shown, 1--transparent conductive layer, 2--electrode, 21--bus bar, 22-inner electrode, 221-single electrode, 5-the first opening, the inner electrode spacing is 6mm, the length is 108mm, a total of 11 Strips, a total of 10 intervals are produced, and the thickness of the silver paste is 25 μm;
[0112] 3. Bake the printed electrode pattern in an oven to solidify the silver paste. The baking temperature is 130°C for 4...
Embodiment 2
[0122] In order to further ensure that the difference between the highest voltage and the lowest voltage at different positions of the bus bar does not exceed 10%, this embodiment adjusts the width of the bus bar and the number of bifurcated electrodes as internal electrodes on the basis of the first embodiment. Specifically: the distance between the internal electrodes is 6 mm, the length is 108 mm, there are 15 bars in total, and 14 intervals are generated in total, and the width of the bus bar is 8 mm.
[0123] After testing, the difference between the highest voltage and the lowest voltage at different positions of the bus bar is 0.5%.
Embodiment 3
[0125] see Figure 6 As shown, the double-layer graphene is used as a low-voltage transparent electrothermal film for heating components, and the preparation process is as follows:
