This study reports a cost-effective molecular design strategy in which phenol is partially substituted with urea to synthesize a sulfomethylated phenol-urea-formaldehyde (SMPU) copolymer. The incorporation of urea enhances hydrophilicity and adsorption onto bentonite while preserving the balance between condensation and sulfomethylation reactions, leading to the formation of a more compact filter cake. At 210 °C (measured at 150 °C and 500 psi), SMPU achieves a high-temperature high-pressure filtrate loss of only 15.6 mL, significantly lower than the 24.8 mL observed for conventional sulfomethylated phenol-formaldehyde resin. The approach also demonstrates clear economic and scalability advantages—raw material costs are reduced by 14.7 % relative to traditional petroleum-based counterparts, and production has been successfully scaled up in a 20 L reactor. Overall, by using amino groups to enhance performance without sacrificing the polymer backbone structure, this work breaks through the long-standing performance limits of traditional fluid-loss reducers, offering a scalable and reliable solution for deep petroleum drilling.","PeriodicalId":405,"journal":{"name":"Polymer","volume":"3 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884656","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}

This contribution reports a homologous family of imidazolium-based polymers with systematically varied hydrophobicity that was used to probe anion-induced phase behavior in aqueous solution. A broad range of anions induces an upper critical solution temperature (UCST) type transition, following closely a reversed Hofmeister series. The ordering is preserved across the polymer family and is commonly reported in the literature. All polymers were derived from a single precursor, which enables direct comparison of ion-specific effects.

In this work, united-atom molecular dynamics simulations are combined with a Sticky Rouse model (SRM) mapping to parameterize Li<ce:sup loc=\"post\">+</ce:sup>–ether oxygen (EO) coordination-related slowdown in PEO-based single-ion-conducting polymer electrolytes. By introducing EO-neutralized tracer chains, we obtain a finite-time, tracer-referenced, chain-level apparent parameter, <ce:math altimg=\"si1.svg\"></ce:math>, that provides a physics-informed reduced-order measure of the apparent dynamical penalty per active Li<ce:sup loc=\"post\">+</ce:sup>-coordinated EO site relative to the composition-dependent matrix background.

Its empirical exponential-like dependence is used as a phenomenological representation of nonlinear coordination-related slowdown and is qualitatively consistent with reported experimental trends. Microscopic analyses show that increasing <ce:math altimg=\"si1.svg\"></ce:math> is correlated with reduced apparent diffusivities, longer Li<ce:sup loc=\"post\">+</ce:sup>–EO coordination lifetimes, reduced EO availability, less favorable multichain solvation, enhanced Li<ce:sup loc=\"post\">+</ce:sup>–TFSI<ce:sup loc=\"post\">−</ce:sup> association, and a redistribution of post-dissociation pathways among dissociation, re-coordination and hopping. These local changes are accompanied by stronger ionic clustering and a reorganization of dynamic heterogeneity at higher salt concentrations, highlighting the mean-field and trend-level scope of the SRM mapping. Because several systems remain subdiffusive within the accessible simulation window, the transport quantities discussed here are interpreted primarily at the trend level. Within this scope, the present work establishes a tracer-assisted SRM parameterization of coordination-related excess drag under composition-dependent matrix slowdown, supporting <ce:math altimg=\"si1.svg\"></ce:math> as an effective descriptor for comparing salt-concentration-dependent transport slowdown.","PeriodicalId":405,"journal":{"name":"Polymer","volume":"6 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884447","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 activated ester polymer poly(pentafluorophenyl lipoate) (pPFPL) is obtained through quantitative initiator-free photopolymerization and is demonstrated to be a reactive homopolymer scaffold for post-polymerization functionalization. PPFPL was modified quantitatively with isopropyl amine, benzyl amine, and PEG methyl ether amine to afford lipoamide homopolymers exhibiting glass transition temperatures ranging from −57 °C to 73 °C. Functionalization with amine mixtures of PEG amine and benzyl amine afforded thermoresponsive copolymers with sharp tunable LCST transitions. Crosslinking of pPFPL with a diamine (feed ratio 0.1–50%) followed by quenching of residual PFP esters with PEG amine gave polylipoamide hydrogels, characterised by swelling and rheological studies. Both the unimeric polylipoamides as well as the networks could be degraded by virtue of their labile backbone disulfides. Interestingly, oxidative conditions were more efficient than reductive conditions, with oxone treatment giving up to 83% reduction in SEC-measured molar mass and hydrogels undergoing full dissolution in water. Overall, pPFPL is established as a versatile, reactive and modifiable platform for designing degradable lipoamide-based materials.","PeriodicalId":405,"journal":{"name":"Polymer","volume":"20 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884361","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}

Inspired by mussels, we developed a PSPT hydrogel based on polyvinyl alcohol, sodium alginate, polydopamine, tannic acid, and borax via a hierarchical crosslinking strategy. This biomimetic structure reinforces dynamic intermolecular interactions and optimizes the polymer network architecture, endowing the PSPT hydrogel with remarkable mechanical properties (29.91 kPa tensile strength, 1654% ultrahigh fracture elongation), rapid autonomous self-healing (96.4% mechanical and 98% electrical recovery within 60 s), and strong, reusable, skin-irritation-free adhesion (up to 61.87 kPa on fabric). As a flexible wearable sensor, the PSPT hydrogel features high sensitivity with a gauge factor up to 3.87, an ultrafast response/recovery time of 0.15 s, and outstanding cyclic stability after 500 loading-unloading cycles. Impressively, the PSPT hydrogel enables real-time monitoring of both subtle physiological activities and large-scale joint motions. Furthermore, it achieves 99.57% character-recognition accuracy for Morse code communication through deep learning, and it also enables intelligent remote control of robotic hands.
