Embodiment 1

[0052] figure 1 and figure 2 A schematic structural diagram of the touch control unit provided in the first embodiment is shown, as shown in figure 1 and figure 2 As shown, the touch control unit provided in the first embodiment includes at least one layer of modified carbon nanotube film layer 1, and the modified carbon nanotube film layer 1 is obtained by modifying carbon nanotubes with strong oxidizing materials. The modified carbon nanotube film layer 1 has high electrical conductivity and low sheet resistance.

[0053] In an example of this embodiment, see figure 1 , the touch control unit includes a layer of modified carbon nanotube film layer 1 . In another example of this embodiment, see figure 2 , the touch control unit includes six layers of modified carbon nanotube film layer 1, the thickness of the six layers of modified carbon nanotube film layer 1 can be the same or different, figure 2 An example is given where the layers have the same thickness. In th...

Embodiment 2

[0058] see image 3 The touch control unit provided in the second embodiment includes three layers of modified carbon nanotube film layers 1, and the modified carbon nanotube film layer 1 is obtained by modifying carbon nanotubes with strong oxidizing materials. The modified carbon nanotube film layer 1 has high electrical conductivity and low sheet resistance.

[0059] Since the conductivity and sheet resistance of carbon nanotubes cannot meet the requirements of touch performance, they need to be modified to make their performance meet the requirements of touch control. In this embodiment, the carbon nanotube film layer is modified to make it To meet the requirements, the modification process of this embodiment is to use strong oxidizing materials such as nitrogen dioxide NO 2 , bromine simple substance Br 2 , HNO nitrate 3 , thionyl chloride SOCl 2 , perfluorosulfonic acid Nafion and / or tetrafluorotetracyanoquinodimethane TCNQF4 to modify the carbon nanotube film layer,...

Embodiment 3

[0062] Embodiment 3 provides a touch control unit, the touch control unit includes at least one layer of modified carbon nanotube film layer, and the modified carbon nanotube film layer is obtained by modifying carbon nanotubes with strong oxidizing materials, The touch control unit also includes a protective layer disposed on the modified carbon nanotube film layer. see Figure 4 and 5 , Figure 4 The shown touch unit includes a modified carbon nanotube film layer 1 and a protective layer 2, Figure 5 The touch control unit shown includes four modified carbon nanotube film layers 1 with different thicknesses and a protective layer 2 arranged continuously.

[0063] The touch control unit described in this embodiment adds a protective layer 2 on the modified carbon nanotube film layer 1 on the basis of the above-mentioned embodiments 1 and 2, because:

[0064] The carbon nanotube structure after surface modification has poor stability, especially when it is exposed to acidi...

Description

technical field [0001] The invention relates to the field of new material synthesis, and in particular to a touch unit, a manufacturing method thereof, and a flexible touch display device. Background technique [0002] The touch units in the prior art are generally made of transparent conductive materials such as ITO (indium tin oxide), metal mash (metal grid), etc., but the mechanical strength and flexibility of these materials are poor, which determines that these materials The manufactured touch unit cannot be well applied to flexible display products. [0003] Although carbon nanotube materials have good mechanical properties and flexibility, the electrical conductivity and sheet resistance of carbon nanotubes cannot meet the performance requirements of touch units, so carbon nanotube materials cannot be well applied to flexible touch controls. product. [0004] Therefore, it is necessary to design a new touch unit structure, which can apply the mechanical properties a...
