In this study, a rigid bio-based diol (VO) containing oxime group is synthesized via the condensation reaction of lignin-derived vanillin and hydroxylamine. Subsequently, VO is introduced into a castor oil-based WPU (CWPU) system to prepare CWPU-VOs with high biobased content. The presence of dynamic oxime-carbamate bonds endowed CWPU-VOs with excellent self-healing (self-healing efficiency>95%, at 80 °C for 1 h,) and reprocessing properties. By adjusting the ratio of VO and castor oil, the mechanical properties of CWPU-VOs (tensile strength of 11.0–24.3 MPa, elongation at break of 642.2–312.0%) can be effectively tuned. In addition, due to the photolysis behavior of oxime-urethane moieties, CWPU-VOs show outstanding fluorescence anti-counterfeiting potential. This work provides a new idea for the development of high-performance waterborne polyurethane with adjustable mechanical properties, self-healing ability, and fluorescent properties.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904914","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 surface morphology and properties of the composite coating are investigated through the transmittance and haze tester, the atomic force microscope (AFM), and the water contact angle. With the addition of AMTHBA, the water contact angle of the coating gradually decreases from 94.1°± 0.5° to 72.6°± 0.5°, and the surface energy increases from 30.8 to 42.1 J m−2. After being immersed in seawater for 28 days, the tensile strength and the elongation at break of PU-25A still kept 3.0 MPa and 136.3%, respectively. The antibacterial performance of the coating increases with the increase of storage time, and the antibacterial rate of PU-25A against Escherichia coli increases from 63.3% to 97.2% after 30 days of storage, and the antibacterial rate against Staphylococcus aureus increases from 59% to 80.1% after 30 days of storage.

Especially, when the the organic compounds are doped into a rigid polymeric matrix, their RTP performances can be greatly enhanced. However, the dispersibility and stability of the organic compounds are difficult to be controlled. Herein, an amorphous homo-polymer (P1) containing naphthalimide units is synthesized and further dispersed into a polyvinyl alcohol (PVA) matrix via a solution mixing procedure. The resultant composites (P1@PVA) exhibit a yellow afterglow under room temperature. In P1@PVA, the naphthalimide chromophores are constrained in an amorphous aggregation state. Unlike in a crystalline state, intermolecular interactions between the amorphous aggregated chromophores are enhanced, while the π–π interaction is weakened. In the presence of PVA, the non-radiative decay can be synergistically suppressed by the external hydrogen bonds and the internal intermolecular interactions. As a results, the RTP performances of P1@PVA are much enhanced. Comparing with the PVA composites containing naphthalimide compounds, the RTP lifetime of P1@PVA is prolonged as 1.5 folds.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091500","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}

However, porous scaffolds often lack desirable osteogenic properties due to the poor hydrophilicity of polymer materials used for FFF technique. In this work, biocompatible materials suitable for FFF technique are prepared by blending polycaprolactone (PCL), polylactic acid (PLA), and tricalcium phosphate (TCP) at various compositions. These composite materials are subsequently printed into cylindrical scaffolds with controllable pore sizes ranging from 200–800 µm, by regulating the infill density during the FFF process. The FFF-printed scaffolds have the highest modulus at a PLA/PCL ratio of 0.7 and a pore size of ≈ 200 µm. Furthermore, surface treatment is applied to these FFF-printed scaffolds in sodium hydroxide solution. As a result, the surface roughness, hydrophilicity and serum adsorption of the scaffolds are significantly enhanced. More importantly, these surface-treated scaffolds can promote the osteogenic differentiation of MC3T3-E1 cells, comparable to commercial Bio-Oss substitutes. Thus, this study offers a cost-effective technique for the development of bioactive scaffolds for potential bone tissue engineering applications.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905301","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}

Traditional methods for preparing these materials often require high temperatures and yield mixtures of products with poor control over structure and properties. To address this, researchers are increasingly using molecular precursors with specific reactive sites that allow for a tunable and well-defined synthesis. This work presents alkyne-terminated cyclotriphosphazenes as promising precursors for synthesizing nitrogen and phosphorus rich graphitic materials with tunable solid-state properties. By applying thermal annealing below 400 °C, it was demonstrated by our groups that precise heating can selectively control ring-opening polymerization of the phosphazene core and crosslinking of terminal acetylenes. Spectroscopic and thermal analysis revealed that slow thermal heating (below 32 °C/min) promotes simultaneous ring-opening polymerization, acetylene crosslinking and graphitization to yield a brittle thin film. In contrast, rapid heating (above 32 °C/min) exclusively induces acetylene crosslinking and graphitization, preserving the cyclotriphosphazene ring and producing a soluble, amorphous black powder. Characterization by electron microscopy and gas absorption analysis confirmed that the fast-heated material has a surface area of 261.03 m2/g, a nitrogen uptake of 822.50 cm3/g, and a significant increase in pore volume. These findings present a new versatile approach for generating carbon-rich, porous graphitic materials for various applications.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/macp.202400412","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905300","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}

Another distinctive feature of pyridine groups is the presence of structural isomers. The effects of pyridine isomers have been investigated, particularly for ortho- and para-substituted pyridines, in relation to their bond formation abilities and interaction energies, which ultimately influence macroscopic physical properties. In this study, the effects of pyridine isomers on the formation of quaternization bonds are newly explored, based on the original design of vitrimer-like materials. The polymer component is a poly(acrylate) random copolymer containing ortho-, meta-, and para-substituted pyridine side groups, which are cross-linked by diiodo molecules through pyridine quaternization bonds. The quaternized pyridines self-aggregate into nano-domains, and bond exchange occurs via trans-N-alkylation in an inter-domain manner. The differences in bond formation and related physical properties of samples with three distinct pyridine isomers, including creep and stress relaxation behaviors of the vitrimer-like materials are investigated. Overall, this study offers new insights into the pyridine isomer effects and provides a fresh perspective for tuning the physical properties of bond-exchangeable materials.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 11","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220170","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}
