Using polyacrylamide (PAM) as a reference, two structurally modified copolymers, namely acrylamide-N,N-dimethylacrylamide copolymer (PAD) and acrylamide-N-vinyl-2-pyrrolidone copolymer (PAN), were synthesized via free radical copolymerization. Polymer solutions were thermally degradation at temperatures ranging from 150 °C to 240 °C for 16 h to simulate downhole high-temperature conditions. The degradation process was comprehensively characterized using Fourier transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance (¹H NMR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), rheological measurements, and thermogravimetric analysis. Results indicate that the degradation of polymers in solution is primarily initiated by the hydrolysis of amide groups, accompanied by main-chain scission and carboxylation reactions, ultimately leading to a significant decrease in system viscosity. Structural analysis reveals that the N,N-dimethylacrylamide (DMAA) units effectively delay amide hydrolysis through steric hindrance effects. In contrast, the rigid cyclic structure in N-vinyl-2-pyrrolidone (NVP) units exhibits excellent thermal stability below 200 °C; however, degradation of the ring structure occurs beyond this temperature, accelerating overall polymer chain scission. Among the copolymers studied, PAN demonstrated the most superior thermal stability. This work underscores the necessity of evaluating polymer thermal stability in solution environments, rather than relying solely on solid-state thermal analysis data, thereby providing crucial theoretical insights for the structural design of high-temperature-resistant polymers tailored for demanding industrial applications, such as ultra-deep well drilling.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"245 ","pages":"Article 111871"},"PeriodicalIF":7.4,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145838546","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}

The extensive reliance on halogen-/phosphorus-based retardants would not only pose the irreversible risk to human health and ecological environment, but also raise the serious sustainability concerns about the progressive depletion of phosphate resources. Moreover, the insertion of these conventional flame retardants would inevitably compromise the mechanical properties of SR materials, which was not feasible for enhancing the application value and scopes in real life. Inspired by hierarchical structure of onion, a halogen-/phosphorus-free and bio-based flame retardant system (CMs@PDA@LDH@MM) was rationally engineered via a hierarchical assembly strategy by integrating renewable glucose-derived carbon microspheres with polydopamine (PDA), Ni-Al layered double hydroxides (LDH), and melamine-malic acid complex (MM). When the content of CMs@PDA@LDH@MM was 16 %, a limiting oxygen index (LOI) of 29.9 % and a UL-94 V-0 rating of SR composites were achieved together with substantial peak heat release rate (PkHRR) reduction of 56 % and smoke production rate (SPR) of 67 %, suggesting the excellent flame retardancy and fire safety performance. This fact was ascribed to the integration of multiple flame-retardant mechanism into a single hierarchical CMs@PDA@LDH@MM hybrid via the synergistic action between catalyzed charring and gaseous dilution/heat absorption ability. Furthermore, SR composites were endowed with the excellent resistance to flame impact and glow-wire ignition (GWFI &gt; 960 °C). Most of all, the mechanical robustness of SR composites was significantly improved with a Young’s modulus increment of 708 % and the elongation at break of 332 %, which would thereby enable the structural self-sustainability under load-bearing condition. In a nutshell, the intrinsic limitation of conventional additive approach was addressed in simultaneously achieving the balanced flame retardancy and mechanical performance, which was expected to provide a new and clean insight for the rational design of sustainable and halogen-/phosphorus-free flame-retardants in the fields of construction and buildings, cables and wire, new energy vehicles and aerospace.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"245 ","pages":"Article 111870"},"PeriodicalIF":7.4,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145789182","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}
