The impact of copolymer composition and grafting time on film stability was examined through the implementation of water performance tests in combination with spectroscopic in situ ellipsometry measurements.

These composites behave like room-temperature polymers but can rapidly transform into ceramics with excellent mechanical properties at elevated temperatures. Achieving ceramification requires amounts of inorganic fillers, which can significantly compromise the material's mechanical and processing performance, while considerably increasing its density. In this study, we successfully fabricate lightweight composites with enhanced ceramifying performance. After vitrification at 800 °C, the sample's flexural strength reaches 21.4 MPa, significantly exceeding the values previously reported in the literature for similar materials. Furthermore, the material's density is only 807.5 kg/m<sup>3</sup>, which is merely 83.5 % of that of the EVA substrate without adding fillers. This reduction in density can significantly reduce production, transportation, and installation costs. Additionally, fire resistance test results show that after 90 min of butane torch ablation, the composite rapidly transforms into ceramic, effectively protecting the internal copper conductor from melting, and the bulb remains lit throughout. The effects of hollow microspheres and flux agents on the sintering process are examined, and the ceramization process and mechanism below 1000 °C are discussed in detail. This lightweight ceramizable composite is important not only for cable sheathing materials but also for developing the materials with a low density and high-temperature resistance.</div></div>","PeriodicalId":405,"journal":{"name":"Polymer","volume":"325 ","pages":"Article 128253"},"PeriodicalIF":4.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608354","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}

We synthesized a range of in-situ silane-terminated polyurethane acrylate (SPUA) resins by modifying the proportions of Vinyltrimethoxy silane (VTMS) and 2-hydroxyethyl methyl acrylate (HEMA) during solution polymerization. Subsequently, the wood and mild steel panels were coated with SPUA hydride resin and cured using UV radiation. UV-curing triggered the initiation of free-radical polymerization, evidenced by the disappearance of C<img>C absorption bands in FT-IR, resulting in the formation of a crosslinked network with the substrate. This resultant coating possesses transparency, a gloss value of 84–90 GU at 60°, high crosslinking (gel fraction >97 %), optimal viscosity (20–40 Pa s), lowered glass transition temperature (71-55 °C), and thermal stability (over 400 °C). The hybrid coating exhibited enhanced water absorption resistance, evidenced by an increased water contact angle (75–95 °C), attributed to a reduction in the surface free energy of the polar component. The strong bonding between the cross-linked silane-terminated polyurethane-acrylate network, and the substrate is the reason behind the significantly improved mechanical properties, including pencil hardness (3H–4H), impact strength (25–35 cm), flexibility (0.2–0.1), solvent rub resistance (>450) and adhesion strength on wood substrate (4.9–7 MPa).

After carboxylation modification, lignin provides more chemical nucleation sites for PET crystallization, which are driven by the ion-cluster-induced nucleation mechanism. In order to explore this modification effect in depth, PET composites with different carboxymethylated lignin contents were prepared and subjected to various characterization analyses, including infrared spectral analysis, electron microscope observation, differential scanning calorimetry test, thermogravimetric analysis, and tensile strength test. The experimental data showed that the composites containing carboxymethylated lignin showed a significant increase in crystallinity and crystallization rate compared to pure PET. Specifically, its crystallinity increased significantly from 20.3 % to 27.7 %, and the crystallization temperature was also significantly increased from the original 199 °C–214 °C.

To determine electrical properties and percolation behavior of composites, different theoretical methods are employed. Specifically, the percolation threshold is identified by detecting the abnormal increase in the composite conductivity slope. Below this threshold, electrical properties are calculated using homogenization theory; after it, the equivalent circuit method is applied. Based on this model, key electrical parameters like conductivity, resistivity, and leakage current are computed for composites with carbon-based, metallic, and ferromagnetic particles in different polymer matrices. Results show good agreement between theoretical predictions and experimental data.
