In this study, we developed a new green fabrication method for silver-coated copper nanowires using methylsulfonylmethane (DMSO2), which is an environmentally friendly chemical at the food-grade level, to replace toxic chemicals, including ammonia, in the silver coating process. Copper nanowires were synthesized under various reaction temperatures and concentrations of hydrazine (N2H4), ethylenediamine (EDA), sodium hydroxide (NaOH), and copper precursor. The reaction temperature higher than 70 \u00b0C caused the oxidation of copper products and evaporation of the sample solution. The optimal conditions to synthesize copper nanowires more than 18 \u00b5m in length and 25\u201345 nm in diameter were determined: 9 M of NaOH, 50 \u00b5L of EDA, 17 mM of CuCl2, 5.7 mM of N2H4, and 70 \u00b0C reaction temperature. Cu-Ag nanowires, which have about a 12 nm thick silver shell, were successfully fabricated at room temperature under 1 mM of silver nitrate (AgNO3) and 1 wt % of DMSO2. Synthesis conditions for copper and silver-coated copper nanowires have been optimized.<\/jats:p>","DOI":"10.3390\/ma15031135","type":"journal-article","created":{"date-parts":[[2022,2,1]],"date-time":"2022-02-01T22:16:18Z","timestamp":1643753778000},"page":"1135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Novel Fabrication of Silver-Coated Copper Nanowires with Organic Compound Solution"],"prefix":"10.3390","volume":"15","author":[{"given":"Suhyun","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Portland State University, Portland, OR 97207-075, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9891-8295","authenticated-orcid":false,"given":"Chien","family":"Wern","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Portland State University, Portland, OR 97207-075, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Portland State University, Portland, OR 97207-075, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2323","DOI":"10.1038\/srep02323","article-title":"Copper nanowires as fully transparent conductive electrodes","volume":"3","author":"Guo","year":"2013","journal-title":"Sci.
