By varying the type of end‐capping alcohol ether, the following plasticizers were prepared: poly (butylene adipate dibutyl ether) (PBADBE), poly (butylene adipate butyl ether) (PBABE), poly (butylene adipate dimethyl ether) (PBADME), and poly (butylene adipate methyl ether) (PBAME). These plasticizers were characterized by Fourier transform infrared (FTIR) spectroscopy, proton nuclear magnetic resonance spectroscopy ( 1 H‐NMR), and thermogravimetric (TG) analysis. Furthermore, their differences in cold resistance, heat resistance, and physical‐mechanical properties in hydrogenated nitrile‐butadiene rubber (HNBR) were investigated. The results showed that among the rubber compounds containing the four polyether‐ester plasticizers, the compound with PBADME demonstrated superior heat resistance and low‐temperature performance. Specifically, the PBADME‐containing compound exhibited a TR 10 temperature of −39.9°C and a brittleness temperature of −54°C. This significantly broadened the operating temperature range of the plasticizer, making it suitable for applications requiring both high‐temperature and low‐temperature performance.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331937","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}

Herein, the lamellar Ti 3 SiC 2 MAX material is prepared via vacuum sintering of a powder mixture containing Ti, Si, and TiC in the molar ratio of 1:1.1:1.8 at 1500°C under a pressure of 30 MPa for 2 h. Combined with a soft graphite phase (5 wt%), self‐lubricating PEEK/Graphite/Ti 3 SiC 2 (PG‐T) composites are successfully prepared, dependent on Ti 3 SiC 2 (5 and 15 wt%) as a hard reinforced phase and lubrication additive. PG‐T composites are fabricated via a multistep compounding approach using a twin‐screw extruder. The incorporation of Ti 3 SiC 2 and graphite within the PEEK matrix manifests a highly pronounced synergistic effect, which not only facilitates effective lubrication but also significantly enhances the load‐bearing capability, thereby effectively circumventing direct contact between the counterface and the polymeric matrix. The sliding tests are conducted on the pins (diameter: 6.0 mm, height: 17.0 mm) and friction pair (45#steel, roughness Ra: 148 nm) under dry friction. In terms of PV‐condition (up to 6 MPa and 3 m/s) (PV is a parameter that reflects the load‐bearing capacity of polymer materials, which is defined by multi‐plying the pressure P by the sliding speed V), PG5‐T15 exhibits self‐lubricating properties, featured by an average coefficient of friction (ACOF) as low as 0.119 for the pin‐plate test and a specific wear rate (SWR) of only 0.58 × 10 −6 mm 3 /Nm. Meanwhile, PG‐T composites present excellent thermal properties based on the thermal expansion coefficients (CTEs) and storage moduli (G′) during friction and wear. Considering the practical applications of tribo‐composites, these findings highlight the potential of PG‐T composite as a candidate for demanding tribological applications.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pat.70128","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal conductivity of polymer‐based composites, as the widely used thermal interface materials, is still limited by the high interfacial thermal resistance between the polymer matrix and the filler.

Under scanning electron microscope observation, the modified carbon fibers dispersed uniformly, and they were adhered to by a number of Ag nanoparticles. The thermal conductivity of the silicone composite with a 20 wt% filling amount of modified carbon fibers reached up to 1.624 W m −1 K −1 , which was 1.46 times higher than that of the unmodified carbon fiber filled silicone composite. The silicone composite with a 20 wt% filling amount of modified carbon fibers also exhibited a relatively high heat transfer rate and excellent mechanical properties. The electrical insulation and dielectric properties of silicone composites filled with modified carbon fibers also satisfied the requirements for the use of thermal interface materials.

The pyrrolidone groups can be protonated to form oxonium ions, functioning as transient fixed positive charges for fractioning sulfuric acid and sulfates via diffusion. The influence of PVC molecular weight and the membrane composition on the physical, chemical properties, and mass transfer performance of PVC‐PVP blend membranes was systematically investigated. After equilibrium in 2.68 mol/L sulfuric acid, the sulfuric acid, and water contents in the blend membranes increase with the increase of the membrane PVP contents (20–75 wt%). The permeability coefficients of sulfuric acid and ferrous sulfate for the blend membranes also exhibit a gradual increase. Membranes of mass transfer properties comparable to commercial ones can be easily obtained by tuning the membrane PVP contents. It is proved that the larger sulfuric acid permeability over sulfates (FeSO 4 as an example) is due to both larger solubility and diffusion coefficient of sulfuric acid in the membrane phase. The optimal PVC‐PVP blend membranes have shown nice performance in fractioning sulfuric acid from sulfates, when treating titania waste acid.

The structure of HPMD has been fully characterized, and the properties of HPMD and modified EP have been thoroughly studied. The phenyl propyl ether group in HPMD can undergo Claisen type rearrangement to form benzopyran during heat treatment and subsequently polymerize by curing via the CC bond in the benzopyran. The unique rigid and flexible structures of HPMD allow it to disperse in the EP matrix through melting. Dynamic mechanical analysis suggests that HPMD has a high degree of interpenetration in the EP matrix, resulting in a single‐phase structure for the epoxy resins containing HPMD. Notably, incorporating only 4 wt% HPMD content into the polymer matrix yields a flame‐retarded, toughened, and strengthened EP. EP containing 4 wt% HPMD (EP4; phosphorus content of only 0.33%) displays a limiting oxygen index value of 31.1% and exhibits a UL94 V‐0 rating. Compared with that of EP, the combustion of EP4 exhibits a decrease in the peak of heat release rate, maximum average heat rate emission, average heat release rate, and total heat release, along with an increase in the char yield, further indicating that HPMD effectively retards the combustion of EP. Moreover, EP4 displays improvements in tensile strength, elongation at break, flexural strength, flexural modulus, and impact strength of 18.4%, 9.7%, 14.9%, 19.1%, and 26.7%, respectively, compared with unmodified EP. Analysis of HPMD's flame‐retardant action suggests that it exhibits flame‐retardant activity simultaneously in the gas and condensed phases. Significant progress has been demonstrated toward the development of a meltable epoxy resin additive that combines flame‐retardant, toughening, and strengthening functions while avoiding phase separation from the epoxy resin.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147902023","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}

Malachite green (MG), fuchsin acid (FA), and crystalline violet (CV) were typical representatives of triphenylmethane dyes, and they are carcinogenic and mutagenic to aquatic organisms and environment. However, they need to be separated and enriched for their accurate quantification due to their low content. Therefore, it is important to develop a rapid and accurate enrichment method to monitor these dyes in aquatic systems for human health. In this paper, a novel QuEChERS adsorbent porous ZIF67/PAA/PES composite microspheres were prepared and applied for the rapid adsorption of triphenylmethane dyes in wastewater and fish samples, which improved the adsorption capacity and the analytical sensitivity of the targets. The experimental results demonstrated that the porous ZIF‐67/PAA/PES composite microspheres exhibited excellent selective adsorption capacity of MG, FA, and CV, and after six adsorption–desorption cycles, the material adsorption amount can reach more than 90% of its original adsorption amount in wastewater. In addition, the porous ZIF67/PAA/PES composite microspheres were applied as QuEChERS adsorbents for the enrichment of MG and CV dyes in fish, and the adsorption rates of the dyes were 99.11% and 99.03%, with the RSDs of 1.58% and 1.27%, respectively.
