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 platforms, 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 thickness, with an 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":"10.3390\/polym18060746","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T08:54:37Z","timestamp":1773910477000},"page":"746","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fabrication of Stochastic Ni@PVP Nanowire Networks for Memristive Platforms"],"prefix":"10.3390","volume":"18","author":[{"given":"Catarina","family":"Lemos","sequence":"first","affiliation":[{"name":"IFIMUP\u2014Instituto de F\u00edsica de Materiais Avan\u00e7ados, Nanotecnologia e Fot\u00f3nica, Departamento de F\u00edsica e Astronomia, Faculdade de Ci\u00eancias, Universidade do Porto, Rua do Campo Alegre s\/n, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1007-3919","authenticated-orcid":false,"given":"Catarina","family":"Dias","sequence":"additional","affiliation":[{"name":"IFIMUP\u2014Instituto de F\u00edsica de Materiais Avan\u00e7ados, Nanotecnologia e Fot\u00f3nica, Departamento de F\u00edsica e Astronomia, Faculdade de Ci\u00eancias, Universidade do Porto, Rua do Campo Alegre s\/n, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1539-7763","authenticated-orcid":false,"given":"Rui S.","family":"Costa","sequence":"additional","affiliation":[{"name":"IFIMUP\u2014Instituto de F\u00edsica de Materiais Avan\u00e7ados, Nanotecnologia e Fot\u00f3nica, Departamento de F\u00edsica e Astronomia, Faculdade de Ci\u00eancias, Universidade do Porto, Rua do Campo Alegre s\/n, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0494-3009","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Ventura","sequence":"additional","affiliation":[{"name":"IFIMUP\u2014Instituto de F\u00edsica de Materiais Avan\u00e7ados, Nanotecnologia e Fot\u00f3nica, Departamento de F\u00edsica e Astronomia, Faculdade de Ci\u00eancias, Universidade do Porto, Rua do Campo Alegre s\/n, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1974","DOI":"10.1038\/s41467-024-45670-9","article-title":"Hardware Implementation of Memristor-Based Artificial Neural Networks","volume":"15","author":"Aguirre","year":"2024","journal-title":"Nat.
