Embodiment 1
[0062] figure 1 It is a schematic diagram of an embedded stretchable metal grid transparent electrode with a shell-core structure to be manufactured in the present invention (1 is a polymer core structure, 2 is a metal shell, 3 is photoresist, and 4 is PET). The parameters of the transparent electrode to be manufactured in this implementation example: the line width is 500 nm; the period is 100 μm; the aspect ratio is 2; the structure shape is grid; the plated metal is copper.
[0063] Taking the transparent electrode described in the embodiment as an example, in combination with Figure 2-Figure 6 , specifying the specific process of preparation based on the proposed method.
[0064] Step 1: Prepare polymer structure printing solution.
[0065] The printing solution consists of poly(4-vinylpyridine) (P4VP, average Mw~160000) from Sigma-Aldrich, N,N-dimethylformamide (DMF) from Aladdin and ethanol (C 2 h 6 O) Preparation.
[0066] Specific process:
[0067] (1) Weigh 30w...
Embodiment 2
[0092] The parameters of the transparent electrode to be manufactured in this implementation example: the line width is 500nm; the aspect ratio is 3; the structure shape is a fractal curve; the plated metal is copper.
[0093] The specific process of preparation based on the proposed method.
[0094] Step 1: Prepare polymer structure printing solution.
[0095] The printing solution consists of poly(4-vinylpyridine) (P4VP, average Mw~160000) from Sigma-Aldrich, N,N-dimethylformamide (DMF) from Aladdin and ethanol (C 2 h 6 O) Preparation.
[0096] Specific process:
[0097] (1) Weigh 40wt% white powdery poly(4-vinylpyridine) (P4VP) with a precision electronic balance and place it in a glass beaker, then weigh 40wt% N,N-dimethylformamide (DMF) and Mix with P4VP (DMF is a good solvent for P4VP, and has a higher dielectric constant, which can easily reduce the formation of beads and fiber diameter), stir with a glass rod until P4VP is completely dissolved in DMF, and finally w...
