Among the various sorbents used in DAC, polymers have emerged as a promising solution, either as active sorbents or as structural supports for active DAC materials, due to their customizable properties, scalability and low cost. This mini-review investigates the latest trends in polymer-based materials for DAC and identifies critical research gaps, such as the need for thorough lifecycle assessments and in-depth studies on the degradation of polymeric materials. It also outlines future directions, emphasizing the importance of developing cost-effective, scalable and durable polymers that can perform efficiently across diverse climatic conditions, including the unique challenges presented by cold weather regions abundant in renewable energy. This mini-review aims to inform ongoing efforts in the design and utilization of polymeric sorbents, providing insights that could guide the development of economically viable and environmentally sustainable DAC technologies. © 2025 The Author(s). <i>Polymer International</i> published by John Wiley &amp; Sons Ltd on behalf of Society of Chemical Industry.</p>","PeriodicalId":20404,"journal":{"name":"Polymer International","volume":"74 8","pages":"651-656"},"PeriodicalIF":2.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pi.6781","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the physical principles underlying the formation of glassy hydrogels with high water content (&gt;50 wt%) at ambient conditions and room temperature to achieve superior mechanical properties are still a subject of active research and debate. The complexity of the bound and confined interactions between polymer chains and water poses significant challenges in unraveling the operational mechanisms behind glassy hydrogels. In this study, by combining non-random lattice theory and free volume theory, an associative rheological model is developed to investigate the thermodynamic and viscoelastic behavior of glassy hydrogels undergoing bound and confined interactions. Drawing upon the principles of rheology, the mechanism for the formation of glassy hydrogels at room temperature is described by spring and dashpot elements, where each mechanical element corresponds to a specific molecular mechanism. The nonlinear behavior of rheology is accurately captured by the lattice structure engaged in these interactions. Our proposed model facilitates a transition between the Maxwell and Voigt models, thereby enabling a comprehensive analysis of key viscoelastic parameters such as storage modulus (<i>E′</i>), loss modulus (<i>E″</i>), loss factor (tan <i>δ</i> = <i>E″</i>/<i>E′</i>) and the observed glass transition phenomena in glassy hydrogels. Finally, the effectiveness of the proposed associative rheological models is verified using the experimental results reported in the literature, offering a principal understanding of the exceptional mechanical properties of glassy hydrogels governed by bound and confined interactions. © 2025 Society of Chemical Industry.</p>","PeriodicalId":20404,"journal":{"name":"Polymer International","volume":"74 8","pages":"727-738"},"PeriodicalIF":2.9,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heat generated during continuous and/or cyclic operation can be dissipated using thermal interface materials (TIMs). A facile yet novel method based on a combination of centrifugal mixing and micropipetting was very effective at accurately depositing thin layers of an epoxy filled with a highly interconnected boron nitride nanosheet (BNNS) network. The use of composites of an epoxy and BNNS as a TIM was assessed by measuring the operating temperature of a diode on a printed circuit board, to replicate in-service use, using thermal imaging. The operating temperature of the device decreased by almost 57 °C on inclusion of a BNNS volume fraction (<i>φ</i>) of 0.15 and the thermal resistance by <i>ca</i> 50%. The device displayed excellent thermal stability and a consistent temperature response during cyclical operations over 10 h. The reliability of transistors depends exponentially upon operating temperature and even a 10–15 °C reduction can double the lifespan of an electronic device. © 2025 The Author(s). <i>Polymer International</i> published by John Wiley &amp; Sons Ltd on behalf of Society of Chemical Industry.</p>","PeriodicalId":20404,"journal":{"name":"Polymer International","volume":"74 7","pages":"553-559"},"PeriodicalIF":2.9,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pi.6770","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144197577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synthesis involves condensation polymerization of 4-mercaptophenol and 4-nitrophenol with formaldehyde to obtain a thiolated/nitro-functionalized polymer that was further reduced to an amino-functionalized polymer (HS-P-NH<sub>2</sub>) using sodium dithionite. Finally, the <i>S</i>-imprinted polymer (S-KP-P) was prepared by imprinting S-KP onto HS-P-NH<sub>2</sub>, followed by post-crosslinking with bis(maleimido)ethane through thiol–maleimide click reaction. Confirmation of the successful functionalization and crosslinking was done via structural characterization techniques. Kinetic studies showed that the crosslinking reaction followed second-order kinetics, with thermodynamic analysis indicating a spontaneous, exothermic process. In the adsorption experiments, S-KP-P manifested better enantioselectivity in the maximum capacity of adsorptions of 422 mg g<sup>−1</sup> for S-KP <i>versus</i> 243 mg g<sup>−1</sup> for R-KP. The Langmuir model provided the best fit to the isotherm data, confirming monolayer adsorption on homogeneous binding sites. Chiral separation experiments using column chromatography demonstrated the ability of S-KP-P to resolve (±)-KP, yielding 97% enantiomeric excess (ee) for R-KP in the first elution and 94% ee for S-KP in the second. In contrast, the non-imprinted polymer showed no enantioselectivity.
