Embodiment 1

[0030] The preparation method of the nano-silver transparent conductive film of this embodiment is specifically carried out according to the following steps:

[0031] 1. Prepare nano-silver wire dispersion: disperse self-made nano-silver wire in an appropriate amount of ultra-pure water, ultrasonically disperse at a frequency of 30KHz for 10 minutes, and stir for 30 minutes;

[0032] 2. Prepare viscosity modifier solution: under vigorous stirring, add hydroxymethylpropyl cellulose (HPMC, manufacturer: Aladdin, Type II, viscosity: 15000mPa.S) into an appropriate amount of pure water at 90°C, disperse for 15min; then keep Stirring state, after cooling to 20°C, pass through a 100-mesh metal mesh sieve to remove colloidal insoluble matter.

[0033] 3. Preparation of surface tension modifier solution: Disperse and fully dissolve the surfactant Sago-9760 in an appropriate amount of pure water;

[0034] 4. Nano-silver wire coating liquid: Mix the above-mentioned nano-silver wire dis...

The product obtained by the invention can promote silver wire lap joint and form an intercommunication network of silver nanowires, so that a transparent conductive thin film with high conductivity, high transparency and large size is obtained, large-scale industrial production can be carried out, and the conductive thin film plays an important role in improving the adhesive force, improving the flexibility of the film and reducing the surface roughness of the film.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a nanometer silver transparent conductive film and a preparation method thereof. Background technique [0002] Transparent conductive film is a kind of film that can conduct electricity and has high transparency in the visible light range, mainly including metal film system, oxide film system, other compound film system, polymer film system, composite film system, etc. However, with the progress of society, in order to meet social needs, the requirements for the conductivity and flexibility of OLEDs also increase. However, the existing transparent conductive film can no longer meet the requirements of OLED for conductivity, transparency, and size. Further development of transparent conductive films with higher conductivity, transparency, and size is required. Contents of the invention [0003] In order to solve the above technical problems, the object ...
