While prior works focused on oxide or silver-based network systems, these approaches face trade-offs between operating voltage, cost, stability, and scalability. This work presents a proof-of-concept demonstration of stochastic polyvinylpyrrolidone (PVP)-coated nickel nanowire networks as low-cost and scalable memristive platform, exhibiting low-voltage resistive switching (1\u20132 V). The electrical characterization reveals predominantly volatile resistive switching combined with nonvolatile behavior, consistent with a filamentary conduction mechanism at nanowire junctions. The switching dynamics are governed by the polymer coating thick-ness, with intermediate PVP concentration (Ni@PVP = 1:25) showing optimal performance, with a resistance ratio of ~ 200, stable retention over 1 h, and a reproducible endurance of over 45 cycles. These results establish Ni@PVP nanowire networks as promising memristive platforms for neuromorphic hardware applications and physical reservoir computing, with relevant properties such as fading memory and nonlinear dynamics.<\/jats:p>","DOI":"10.20944\/preprints202603.0293.v1","type":"posted-content","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T01:07:37Z","timestamp":1772759257000},"source":"Crossref","is-referenced-by-count":0,"title":["Fabrication of Stochastic Ni@PVP Nanowire Networks for Memristive Platforms"],"prefix":"10.20944","author":[{"given":"Catarina","family":"Lemos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catarina","family":"Dias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1539-7763","authenticated-orcid":false,"given":"Rui S.","family":"Costa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0494-3009","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Ventura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","container-title":[],"original-title":[],"deposited":{"date-parts":[[2026,3,25]],"date-time":"2026-03-25T06:06:51Z","timestamp":1774418811000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.preprints.org\/manuscript\/202603.0293\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.20944\/preprints202603.0293.v1","relation":{"is-preprint-of":[{"id-type":"doi","id":"10.3390\/polym18060746","asserted-by":"subject"}]},"subject":[],"published":{"date-parts":[[2026,3,4]]},"subtype":"preprint"}}
