The electronic paper comprises an electrode panel 1, a film layer 4, a display slurry layer 2 and a circuit driving layer 3 which are sequentially stacked, wherein the film layer 4 is formed by performing silane coupling agent treatment on the surface of one side, close to the display slurry layer 2, of the electrode panel 1.
The electrode surface treatment method of the electronic paper comprises the following steps:
s1: preparing a silane coupling agent solution (total weight is 100%): adding 1% of 1H, 2H-perfluorooctyl trimethoxy silane, 3% of isopropanol and 96% of pentafluorobenzene into a beaker according to the weight ratio, stirring for 30min to obtain a silane coupling agent solution, and sealing for later use;
s2: removing the electrode panel 1, wiping off greasy dirt on the surface of one side of the electrode panel 1, which is close to the display slurry layer 2, with ethanol, standing for 10min, and airing; in a dust-free environment, wrapping the side edge of the electrode panel 1 and the surface of the electrode panel 1, which is far away from the display slurry layer 2, by using a PE protective film; placing the electrode panel 1 close to the surface of the slurry display side 2 upwards to expose the area to be sprayed;
s3: spraying the silane coupling agent solution on the surface of the electrode panel 1, which is close to the side of the display slurry layer 2, standing for 30min, and heating for 1h to 100 ℃; heating for 0.5h to 180 ℃ to volatilize the isopropanol and the fluorocarbon solvent and solidify the silane coupling agent solution; and (3) wiping residual liquid on the surface of the electrode panel 1 by adopting ethanol to obtain a film layer 4.
Finally, the display slurry layer 2 and the circuit driving layer 3 may be further bonded to the film layer 4 to obtain electronic paper.
Example 2
This example is substantially the same as example 1 except that trimethoxy (1H, 2H-nonafluorohexyl) silane is selected as the fluorosilicone coupling agent.
The electronic paper is manufactured by bonding the electrode panel 1 treated by the surface treatment method with the display slurry layer 2 and the circuit driving layer 3.
Example 3
This example is substantially the same as example 2, except that the amounts of trimethoxy (1H, 2H-nonafluorohexyl) silane and fluorocarbon solvent added are different. In this example, 3% trimethoxy (1H, 2H-nonafluorohexyl) silane and 94% pentafluorophenyl were added.
The electronic paper is manufactured by bonding the electrode panel 1 treated by the surface treatment method with the display slurry layer 2 and the circuit driving layer 3.
Performance testing
The electronic papers obtained in examples 1 to 3 were tested for service life with a TFT tester under the following conditions: applying a voltage of plus or minus 15V and a frequency of 10HZ; the test objects are: 4 electronic papers of each of examples 1 to 3 and conventional electronic papers (electronic papers not treated by the surface treatment method provided herein, that is, the difference from the examples is that there is no film layer 4, all the other are the same); and (3) analysis and comparison: the average value was taken for analysis.
The time for obtaining obvious afterimage of the electronic paper (namely the service life of the electronic paper) is shown in the following table:
table 1 test results of the service lives of the electronic papers in example 1
Table 2 test results of the service lives of the electronic papers in example 2
Table 3 test results of the service lives of the electronic papers in example 3
Analyzing tables 1 to 3, and obtaining that the service life of the electronic paper obtained by the electrode surface treatment method of the electronic paper provided by the application in the embodiment 1 to the embodiment 3 is greatly prolonged compared with that of the electronic paper which is not treated, the service life of the electronic paper is prolonged from 14.75 hours to 26.75 hours in the embodiment 1, the whole time is prolonged by 12 hours, and the service life of the electronic paper is prolonged by 81.36 percent compared with that of the conventional electronic paper; in the embodiment 2, the time is increased from 14.25h to 23.75h, the time is increased by 9.5h, and the service life is prolonged by 66.67 percent compared with the conventional electronic paper; in the embodiment 3, the time is increased from 14.5 hours to 26.75 hours, the time is increased by 12.25 hours, and the service life is prolonged by 84.48 percent compared with the conventional electronic paper.
This is because the adsorption of the fluorosilicone coupling agent forms a transparent, closed film layer 4 between the electrode panel 1 and the display slurry layer 2; the film layer 4 enables the electrode panel 1 and the display slurry layer 2 to generate a certain gap, so that the adsorption effect of the electrode panel 1 on the electrophoresis particles in the display slurry layer 2 is weakened; one side of the film layer 4 is silanol group condensed on the surface of the electrode panel 1 to form a colorless transparent organic silicon network, and the other side of the film layer 4 contains groups with different polarities from those of the electrophoretic particles in the display slurry layer 2, so that the compatibility between the two groups is weakened, and the adsorptivity of the electrophoretic particles on the surface of the electrode panel 1 is further reduced. Therefore, the electrophoretic particles are positioned in the display slurry layer 2 and can stably move, so that the display effect is ensured, and the problem of residual shadow on the surface of the electrode is reduced.
Table 1 and Table 2 are compared, and since examples 1 and 2 differ only in the kind of fluorosilicone coupling agent, example 1 is 1H, 2H-perfluorooctyl trimethoxysilane and example 2 is trimethoxy (1H, 2H-nonafluorohexyl) silane. From the test results in tables 1 and 2, 1H, 2H-perfluorooctyl trimethoxysilane worked slightly better than trimethoxy (1H, 2H-nonafluorohexyl) silane.
Comparing tables 2 and 3, since example 2 and example 3 differ only in the amount of trimethoxy (1 h,2 h-nonafluorohexyl) silane and fluorocarbon solvent, it can be concluded that the service life of electronic paper can be effectively improved by increasing the amount of trimethoxy (1 h,2 h-nonafluorohexyl) silane.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
