Embodiment 1

[0023] Embodiment 1, 5g oil-soluble nano-silver is dissolved in 3.2g normal hexane, add 1.5g epoxy resin E-45 while stirring, 0.2g cross-linking agent tetraethyldiethanolamine, 0.1g surfactant dodecane Dimethyl betaine, after stirring evenly, spray "U" pattern on the plexiglass. Afterwards, the plexiglass was sintered at 130°C for 20 minutes, and the nano-silver wire was formed.

Embodiment 2

[0024] Embodiment 2, oil-soluble nano-silver cyclohexane dispersion liquid 6g (silver content is 4g) is added in the 2.2g normal hexane, adds 1g epoxy resin E-45, 0.11g tetraethyldiethanolamine while stirring, After stirring well, add about 0.1g OPE to adjust the viscosity. After fully mixing, spray "U" pattern on the plexiglass plate. Afterwards, the plexiglass was sintered at 130°C for 20 minutes, and the nano-silver wire was formed.

Embodiment 3

[0025] Example 3: Add 5 g of oil-soluble nano-silver to 2.5 g of n-hexane, add 2 g of epoxy resin E-45 and 0.2 g of tetraethyldiethanolamine while stirring, add about 0.3 g of OPE to adjust the viscosity after fully stirring. After fully mixing, spray "U" pattern on the plexiglass plate. Afterwards, the plexiglass was sintered at 130°C for 20 minutes, and the nano-silver wire was formed.
