Composites with hybrid nanofillers containing multiwalled carbon nanotubes, graphene nanoplatelets, and aluminum trihydrate were aged at 120°C and 160°C for 3000 h. Thermal aging induced chemical degradation, with a 10-fold increase in oxidation rate at 160°C due to chain scission. Carbonyl formation and hydroperoxide intermediates were formed in the composites. Tensile strength reduction of 8.6% in base composites is observed compared to 6.5% in the nanocomposite with hybrid nanofillers. Hybrid nanofillers reduce degradation by limiting oxygen diffusion, cooling the matrix, and stabilizing <i>T</i>\u0000 <sub>\u0000 <i>g</i>\u0000 </sub>, outperforming literature-reported reductions of 7%–12% for similar composites. Thermal conductivity, modeled using Maxwell–Garnett, shows an enhancement of 40%–60% with nanofiller content and 10%–20% in the Bruggeman model. This slows heat diffusion, further mitigating aging. Transient heat flow analysis confirmed a 20%–30% longer diffusion time enhancing thermal stability. The nanocomposite retained 474.56 MPa tensile strength post-aging, meeting high-temperature low-sag (HTLS) conductor standards.

This radiation can initiate free radical reactions that compromise the structural integrity of the polymer and deteriorate its mechanical properties. The addition of photostabilizers can reduce the rate of photodegradation in the polymer significantly. In this study, PMMA was first modified with hydrazine and then separately functionalized with four different aromatic aldehydes, namely 2-nitrobenzaldehyde, 4-nitrobenzaldehyde, 3,4-dimethoxybenzaldehyde, and 4-bromobenzaldehyde.

This study investigates the mechanical and rheological properties of poly(vinylidene fluoride-co-chlorotrifluoroethylene) (PVDF-CTFE) synthesized using traditional PFAS-based methods and new “no added PFAS” approaches. Various synthesis parameters such as reaction temperature, agitation speed, and initiator concentration were varied to produce several polymer lots. The resulting PVDF-CTFE polymers were evaluated by gel permeation chromatography, rheology, and tensile testing to assess various replacements for the legacy (i.e., added PFAS) material. Our findings indicate that the “no added PFAS” PVDF-CTFE can achieve mechanical and rheological performance comparable to traditional methods, with certain lots (i.e., 2059) closely matching the legacy lot (i.e., 30035) due to its relatively low molecular weight when compared with other lots. The tensile strength, elongation, and viscoelastic properties from tensile testing, in-situ pressure monitoring during compounding, and parallel plate rheology all agreed that due to its relatively low molecular weight, lot 2059 was the most appropriate replacement for 30035. This work provides a foundational understanding of how synthesis variations to eliminate added PFAS can be tuned to create materials with similar properties as those made with PFAS, guiding future developments in environmentally safer fluoropolymer production.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Highlights</h3>\u0000 \u0000 <div>\u0000 \u0000 <ul>\u0000 \u0000 <li>PFAS-free PVDF-CTFE evaluated.</li>\u0000 \u0000 <li>Mechanical properties approached PVDF-CTFE made with PFAS.</li>\u0000 \u0000 <li>Varied synthesis impacts assessed.</li>\u0000 \u0000 <li>Guides eco-friendly polymer production.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"32 1","pages":"6-17"},"PeriodicalIF":3.6,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145941592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
