Embodiment Construction
[0039] Please refer to figure 1 Shown, the present invention discloses a kind of manufacturing method of silver nanowire, it comprises the steps:
[0040] (a). A mixed solution is provided, containing at least one protective agent and an additive in the mixed solution, the additive being a halide and / or a compound capable of forming an intolerable salt with silver ions;
[0041] (b). Provide a silver precursor solution containing silver compounds, and add the silver precursor solution to the mixed solution at least twice;
[0042] (c). Separating and obtaining the silver nanowires.
[0043] Specifically, in step (a), the protective agent includes but is not limited to:
[0044] Various molecular weight polyvinylpyrrolidone (PVP, (C 6 h 9 NO)n), derivatives of polyvinylpyrrolidone, polyvinyl alcohol (PVA, (C 2 h 4 O)n), polyethylene oxide (PEO, (CH 2 CH 2 O) n), sodium lauryl sulfate (C 12 h 25 SO 4 Na), dodecylamine (C 12 h 27 N), octadecylamine (CH 3 (CH 2 ) 1...
