Silver nanowire touch electrode unit and preparation method and application thereof

The invention relates to a silver nanowire touch electrode unit and a preparation method and application thereof. The preparation method comprises: preparing the first protective adhesive layer on the surface of the transparent substrate; a first hydrophobic coating is prepared on the surface of the first protective glue layer and etched, first grooves arranged in an array mode are obtained, and the depth of the first grooves is equal to the thickness of the first hydrophobic coating; the first groove is filled with a precursor mixture, the polar solvent is removed after ultraviolet irradiation, first electrodes arranged in an array mode are obtained, and the precursor mixture comprises silver nanocrystal seeds, a silver source and the polar solvent; stripping the etched first hydrophobic coating, and preparing a second protective adhesive layer on the surface of the first electrode; the preparation steps of the first grooves and the first electrodes are repeated, second grooves and second electrodes which ar
