Embodiment 1
[0021] The glass light guide plate of this embodiment includes a glass substrate, the glass substrate is a cuboid, and the six sides of the cuboid are provided with graphene layers.
[0022] The preparation method of the glass light guide plate of this embodiment comprises the following steps:
[0023] 1) Use deionized water to ultrasonically clean the glass substrate for 30 minutes, then place the cleaned glass substrate in a quartz tube, and then place the quartz tube in a high-temperature furnace;
[0024] 2) One end of the quartz tube is connected to the carbon source, and the other end is connected to the mechanical pump;
[0025] 3) Vacuumize the inside of the quartz tube to a range of 0.5-1.5Pa through a mechanical pump;
[0026] 4) When the temperature in the high-temperature furnace is raised to 450°C, a methane carbon source is introduced into the furnace, and the temperature is kept at 450°C for 3 hours, that is, a graphene layer is deposited on the six sides of th...
Embodiment 2-7
[0028] The difference between Examples 2-7 and Comparative Examples 1-4 and Example 1 is that the specific experimental parameters involved in the process of preparing the glass light guide plate by the plasma-assisted chemical vapor deposition method are different, see Table 1 and Table 2 for details , and the light transmittance and aging resistance of the glass light guide plates in Examples 1-7 and Comparative Examples 1-4 were tested, and the results are shown in Table 1 and Table 2.
[0029] Test parameters and light transmittance test results in Table 1 embodiment 1-4 and comparative example 1
[0030]
[0031] Test parameter and light transmittance test result in table 2 embodiment 5-7 and comparative example 2
[0032]
[0033] From the data in Table 1 and Table 2, it can be seen that the rate and time of introducing carbon source have a great influence on the optical properties of the graphene layer, and the rate of introducing methane gas is at 0cm 3 / min-6cm...
Embodiment 8
[0035] The glass light guide plate of this embodiment includes a glass substrate, the glass substrate is a cuboid, and the six sides of the cuboid are provided with graphene layers.
[0036] The preparation method of the glass light guide plate of this embodiment comprises the following steps:
[0037] 1) Use ethanol to ultrasonically clean the glass substrate for 30 minutes, then place the cleaned glass substrate in a quartz tube, and then place the quartz tube in a high-temperature furnace;
[0038] 2) One end of the quartz tube is connected to the carbon source, and the other end is connected to the mechanical pump;
[0039] 3) Vacuumize the inside of the quartz tube to a range of 0.5-1.5Pa through a mechanical pump;
[0040] 4) When the temperature in the high-temperature furnace is raised to 500°C, the ethane carbon source is introduced into the furnace, and kept at 500°C for 2 hours, that is, the graphene layer is deposited on the six sides of the glass substrate, and t...
