Isothermal FTIR analysis, interpreted using Kamal\u2019s autocatalytic model and model-free isoconversional DSC analysis, showed that the presence of amino-functionalized nanotubes accelerates the initial epoxy curing reaction, increasing the primary reaction rate constant, reducing the activation energy, and confirming the catalytic role of the nanotube surface amino groups. Thermal\u2013mechanical analysis indicated the formation of an interphase characterized by locally reduced crosslink density resulting from reactions between the functionalized nanotubes and the epoxy precursor. This interphase slightly lowers the glass transition temperature and the onset of thermal degradation without significantly affecting the overall thermomechanical performance. The incorporation of the filler also produces a remarkable increase in electrical conductivity, with an electrical percolation threshold between 0.1 and 0.3 wt%. Conversely, moisture diffusion and equilibrium water uptake remain essentially unchanged, demonstrating that the low nanotube content does not significantly alter the diffusion pathways or the polarity of the crosslinked network.<\/jats:p>","DOI":"10.3390\/polym18172087","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T18:33:52Z","timestamp":1787942032000},"page":"2087","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Amino-Functionalized DWCNTs Tailor Curing Kinetics and Multifunctional Performance of Epoxy Nanocomposites"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2727-2930","authenticated-orcid":false,"given":"Raffaele","family":"Longo","sequence":"first","affiliation":[{"name":"Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, SA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5839-1321","authenticated-orcid":false,"given":"Liberata","family":"Guadagno","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, SA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1963-9472","authenticated-orcid":false,"given":"Marialuigia","family":"Raimondo","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, SA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3684-9184","authenticated-orcid":false,"given":"Francesca","family":"Aliberti","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, SA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4448-6984","authenticated-orcid":false,"given":"Michelina","family":"Catauro","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Campania \u201cLuigi Vanvitelli\u201d, Via Roma 29, 81031 Aversa, CE, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Luigi","family":"Vertuccio","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Campania \u201cLuigi Vanvitelli\u201d, Via Roma 29, 81031 Aversa, CE, Italy"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2100429","DOI":"10.1002\/mame.202100429","article-title":"Recent advances in boron nitride based hybrid polymer nanocomposites","volume":"306","author":"Aparna","year":"2021","journal-title":"Macromol.
