Herein, the effects of multiple factors including strain rate, temperature, humidity and chemical attack on the constitutive response and fatigue behavior of PFSA ionomers were investigated using multiple in-situ testing means with monotonic tension and fatigue crack propagation. The results demonstrate that under high hygrothermal conditions, PFSA ionomer exhibit a decrease in strength and stress relaxation resistance accompanied by increased ductility, with enhanced temperature sensitivity, while nonlinear accumulation of damaged side chains and backbone with corrosion time results in increased brittleness and rigidity after chemical corrosion. Increases in both stress ratio and hygrothermal conditions promote crack propagation, whereas higher loading frequencies inhibit it, and following 72 h of corrosion, the crack propagation rate exhibits a two order of magnitude increase. Under high hygrothermal conditions, fracture surface ligaments exhibit more pronounced serration features and develop a tendency to curl and elongate, while following chemical corrosion, teardrop-shaped pore morphologies emerge in the crack nucleation region, and circumferential slender ligaments develop in the advanced stages of crack propagation. Based on these results, a fatigue joint damage mechanism of PFSA ionomer under the combined effects of hygrothermal conditions and chemical corrosion is proposed.</div></div>","PeriodicalId":405,"journal":{"name":"Polymer","volume":"333 ","pages":"Article 128678"},"PeriodicalIF":4.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the butene-1/ethylene copolymer with 4.3 mol% ethylene co-units (PB8220 M) filaments were used for hot stretching at different temperatures. And the effect of hot stretching on the macroscopic properties and structural evolution of the filaments were investigated by in situ small-angle X-ray scattering (SAXS)/wide-angle X-ray scattering (WAXS), combined with ex situ SAXS and differential scanning calorimetry (DSC) measurements. The results indicate that the filaments exhibit a “shish-kebab” structure for all stretching temperatures. As the hot stretching progresses, the kebab crystals (lamellae) experience partial melting, followed by recrystallization to form shish crystals under stress. And the average lengths of shish crystals at all stretching temperatures first increase and then gradually decrease with the strain due to gradual growth and subsequent fracture. Higher temperature enhances the chain mobility and accelerates the transformation of crystal structure, promoting the formation of longer shish crystals, thus improving the mechanical properties of filaments.

While graphene modification is widely studied, there is still a need for a multiscale framework to analyze how the structural parameters govern interfacial mechanical properties and influence the overall mechanical performance of composite. In this study, a multiscale modeling framework integrating molecular dynamics (MD) and finite element modeling (FEM) was developed to link the nanoscale graphene structure to macroscale composite performance through cohesive zone modeling (CZM). Through MD simulations, the traction-separation (T-S) responses under tensile, shear, and mixed-mode failure were obtained. The simulation results reveal that the addition of graphene layers enhances interaction between fiber surface and resin matrix by increasing fiber surface area. However, excessive graphene height or density leads to reduced interfacial mechanical performance. Furthermore, a uniform graphene layer alignment significantly improves interfacial fracture performance. These atomic derived insights were subsequently incorporated into a cohesive zone model, enabling FEM to evaluate how structure parameters impact macroscale mechanical performance. The results show that the improved interfacial mechanical properties translate into improved composite strength by enhancing macroscale load transfer efficiency.
