In this study, waterborne non-isocyanate polyurethane (WNIPU) latexes, exclusively stabilized by cellulose nanocrystals (CNCs) and partially derived from renewable resources, were synthesized for the first time via suspension polymerization. A polyaddition reaction between a siloxane diamine and 1,6-hexanediol bis(cyclic carbonate) occurred within the monomer-in-water Pickering emulsion droplets effectively stabilized with CNCs. The concentration of the CNCs was optimized for the Pickering emulsion. The CNCs acted as nanoparticle surfactants on the surface of the WNIPU latex particles, as confirmed using rhodamine B-labelled CNCs and confocal laser scanning microscopy. Spherical-shaped monomer droplets and WNIPU latex particles with a median size of 10 μm were achieved. The effect of the cyclic carbonate-to-amine molar ratio on the amine monomer conversion, molecular weight, and thermal properties of the WNIPU was investigated. The obtained WNIPU suspensions exhibited fluorescence under UV irradiation at 365 nm owing to the clustering of carbamates. Combining the fluorescence properties with low glass transition temperatures, these latexes open various potential applications as functional coatings.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 29","pages":" 3351-3361"},"PeriodicalIF":4.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/py/d5py00341e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144341308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we successfully achieved Ugi five-component polymerization (Ugi-5CP) of CO2 and 5-hydroxymethylfurfural (HMF) derivatives to prepare functional polyfurans at room temperature, without the use of metal catalysts. Furthermore, the Ugi-5CP method was extended to various diamines and dialdehydes, producing polyfurans with satisfactory molecular weights (up to 14 400 g mol−1), reasonable yields, and good solubilities. The Ugi-5CP facilitated the incorporation of functional units, including furan, amide, and urethane. Theoretical calculations confirmed the formation of intramolecular hydrogen bonding between the oxygen atom in the furan ring of the main chain and the hydrogen atom in the amide of the side group. Benefiting from the regulation of inter- and intramolecular hydrogen bonding by the furan moiety, the resulting polyfurans exhibited unique nonconventional fluorescence behavior, excellent film-forming ability, and a high strength of 12.0 MPa with an elongation at break of 366.9%. Therefore, this work not only introduces a novel strategy for copolymerization using CO2 and bio-based platform chemicals but also provides valuable insights into the regulatory mechanism of multi-component polymerization on the properties of bio-based polymers.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 28","pages":" 3228-3236"},"PeriodicalIF":4.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319603","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}

Polymersomes are capsule-like structures self-assembled from amphiphilic polymers that can function as carriers. Although the sudden release of cargo has been achieved by inducing the overall structural collapse of polymersomes, the gradual release of cargo, which is key for decreasing the number of drug-administration cycles, remains a challenge. Disulfide crosslinking is one of the candidates for controlling the releasing ability of polymersomes. However, such previous research only focused on strategies for oxidation of thiol to induce disulfide crosslinking under oxidative conditions, which missed the potential for the disulfide crosslinking under reductive conditions. Herein, we realize a new strategy that disulfide crosslinking can be induced under reductive conditions. Amphiphilic polymers with multiple disulfide bonds were newly synthesized, and they self-assembled into polymersomes that facilitate the gradual release of cargo in a reductive environment. The addition of glutathione facilitated the successive crosslinking of the disulfide bonds in the membranes, resulting in a rigidified membrane structure. The changes in the membrane rigidity influenced the permeability of the cargo in the polymersome, resulting in its controlled release. We expect that our study will expand molecular design strategies to control the membrane properties of polymersomes.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 28","pages":" 3258-3264"},"PeriodicalIF":4.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/py/d5py00273g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, most research focuses on neutral porous organic polymers. However, these materials only adsorb guest molecules matching their pore dimensions due to the limitation of the cavity size, which restricts their application field. To address this issue, two cationic porous organic polymers (CTN-POPs, CTN-POP-1 and CTN-POP-2) were prepared from 1,1′-bis(2,4-dinitrophenyl)-4,4′-bipyridinium dichloride (1) with 5,10,15,20-tetra(4-aminophenyl)porphyrin (2) and 1,1,2,2-tetrakis(4-aminophenyl)ethene (3) via the Zincke reaction, respectively. N2 adsorption experiments confirmed the porosity of CTN-POPs at 77 K. Furthermore, CTN-POPs displayed high CO2/N2 selectivity at 273 and 298 K, and the dynamic breakthrough experiment of CTN-POP-1 further verifies the dynamic separation performance for CO2 and N2 at 273 K. In the solution adsorption study, CTN-POP-1 exhibited higher adsorption capacity for anionic dyes and drugs owing to its porous structure and polycationic property. Moreover, the release ratios for dye-2 and drug-3 reached 96.9% and 99.3% in CTN-POP-1⊃dye-2 and CTN-POP-1⊃drug-3, respectively. Therefore, compared to neutral porous materials, CTN-POPs not only compensate for the traditional limitation of pore size-dependent adsorption performance but also expand the diversity of their application fields. Thus, this study provides an effective strategy for constructing functional materials to relieve the greenhouse effect, purify water resources, and promote drug delivery.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 27","pages":" 3129-3137"},"PeriodicalIF":4.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305444","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}

However, their reliance on petroleum-based precursors and permanent crosslinked networks hinders recyclability, thereby creating environmental challenges. Although existing methods to introduce degradable bonds can improve recyclability, they often compromise thermal performance. To address these issues, we adopted a “rigid conjugated dynamic dihydrazone bond + bio-based synergy” strategy and designed a bio-based benzoxazine resin by synthesizing dihydrazone-containing bisphenol monomers from bio-vanillin and hydrazine hydrate, followed by polymerization with furfurylamine. This strategy incorporated acid-labile dynamic bonds into the crosslinked network while preserving thermal stability. The resin exhibited a char yield of 59.5% at 800 °C, comparable to those of petroleum-based analogues. Moreover, the dynamic network enabled controlled degradation under three conditions: elevated temperature, acetone–water mixtures (2 : 8, v/v), and 0.1 M HCl at 50 °C. In carbon fiber composites, 96% of the original fiber strength (2.64 vs. 2.75 GPa) was retained after 24 hours of resin decomposition, with minimal surface damage. This work demonstrates a bio-based approach for balancing thermal performance and recyclability in thermosetting composites, providing a practical pathway toward sustainable high-performance materials.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 29","pages":" 3296-3309"},"PeriodicalIF":4.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305443","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}
