I am trying from last 6 months to synthesize silver nanowires...but in result we only get nanoparticles...we are synthesizing through polyol process can anyone please tell me how to synthesized it...thank you
Dear Summiya Yousafzai , there is extensive bibliography about the synthesis of silver nanowires, may be you find some of the following useful for your work:
https://pubs.rsc.org/en/content/articlelanding/2018/nr/c8nr02242a#!divAbstract
In this article, the authors made a modification to the polyol method and they found that the addition of propylene glycol to ethylene glycol-based polyol synthesis facilitated the growth of Ag NWs with large yield and very fast (5 min)!
Article Simple and Fast High-Yield Synthesis of Silver Nanowires
In this paper the authors modify the common polyol method to overcome the problem of Ag nanoparticle contamination, obtaining clean nanowires.
Article One-Step Synthesis of Silver Nanowires with Ultra-Long Lengt...
In this one the authors combine KBr and NaCl to tackle the problem of Ag nanoparticles and facilitate the formation the nanowires.
Probably you can search for yourself some alternatives, directly on the web or through RG search tool.
Hope this helps. Good luck!
Dear Summiya Yousafzai thank you for asking this interesting technical question. I think that Manuel Gómez already provided a very good and helpful answer. Let me just add that it often pays off to directly search the "Publications" section of RG to find and access relevant links on a certain topic. For example, just search for the term "silver nanowire" and then click on "Publications". This will provide you with a long list of research articles which have been posted by RG members, many of them even as public full texts:

Even a "green" synthesis of silver nanowires has been reported in the literature:
Preparation of Silver Nanowires via a Rapid, Scalable and Green Pathway
Article Preparation of Silver Nanowires via a Rapid, Scalable and Gr...
Good luck with your research and best wishes!
Dear Summiya Yousafzai,
As the above experts' suggestion, i will give you more insights from my own experiences. You need to pay an attention to the polymer you use in your synthesis. The molecular weight of the polymer is the key to obtain silver nanowires. If you use the low molecular weight such as 10,000 of a polymer, you likely get nanoparticles instead of nanowires. 45,000 to 60,000 MW are good to obtain nanowires.
The second factor is the duration of synthesis. You need to control the reaction time and monitor colour changing. There are more papers you could find it easily as suggested.
Best of luck

Dear Summiya,
Please proceed with this paper. Article Scalable Coating and Properties of Transparent, Flexible, Si...
As suggested by Xuhua Wang , please use higher molecular weight of PVP.
Best Regards

Hi,
You can try using the method described in the following paper: "L. Hu et al, ACS Nano 4 (2010) 2955-2963". This method worked very well for me. The synthesis yield is quite good and the procedure is very simple.
We provide researchers with low-cost electrodeposited metallic nanowires, having different lengths and diameters. Contact: [email protected]
Polyol method - Silver nanowires are produced using an aqueous solvent in an autoclave at 120° C for 8h. Rapid synthesis – Silver nanowires are prepared by mixing polyvinyl pyrrolidone and copper chloride in disposable glass vials. In this method, ethylene glycol is used as a precursor to the reducing agent.
Silver nanowires (AgNWs) combine high electrical conductivity with low light extinction in the visible and are used in a wide range of applications, from transparent electrodes, to temperature and pressure sensors.
