Firstly, an MOF material, ZIF-8-NH₂, was synthesized through the self-assembly of metal ions and organic ligands at room temperature. ZIF-8-NH₂ was then reacted with glycidyl methacrylate (GMA) to form ZIF-8@GMA. Finally, ZIF-8@GMA-PHFBA was prepared by grafting fluorinated monomer 2,2,3,4,4,4-hexafluorobutyl acrylate (HFBA), from the ZIF-8@GMA surface <i>via</i> photoinduced ATRP under 365 nm UV light. The structural evolution during the metal-free ATRP modification of ZIF-8-NH₂ was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and thermogravimetry analysis (TGA). The test results verified that ZIF-8-NH₂ and ZIF-8@GMA-PHFBA were successfully synthesized, and that the surface graft polymerization did not change the structure and morphology of ZIF-8-NH₂. After anchoring the ZIF-8@GMA-PHFBA hybrid material on the fabric surface, the water contact angle (WCA) of the ZIF-8@GMA-PHFBA hybrid material-modified fabric surface reached 154.2°, which achieved a superhydrophobic state. In addition, the oil-water separation experiment and self-cleaning test demonstrated that the ZIF-8@GMA-PHFBA hybrid material-modified fabric has an excellent oil-water separation effect and self-cleaning performance. This material shows promising potential for applications in self-cleaning and oil-water separation technologies.</p></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"43 10","pages":"1850 - 1862"},"PeriodicalIF":4.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242656","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}

Experiments have shown that pressure plays a pivotal role in regulating the microscopic chain conformation of polymers in mixed solvents, and one notable finding is that increasing the pressure can lead to the vanishing of the co-nonsolvency effect. However, the mechanisms underlying this phenomenon remain unclear. In this study, we systematically investigated the influence of pressure on the co-nonsolvency effect of single-chain and multi-chain homopolymers in binary mixed good-solvent systems using molecular dynamics simulations. Our results show that the co-nonsolvency-induced chain conformation transition and aggregation behavior significantly depend on pressure in all single-chain and multi-chain systems. In single-chain systems, at low pressures, the polymer chain maintains a collapsed state over a wide range of co-solvent fractions (x-range) owing to the co-nonsolvency effect. As the pressure increases, the x-range of the collapsed state gradually narrows, accompanied by a progressive expansion of the chain. In multichain systems, polymer chains assemble into approximately spherical aggregates over a broad x-range at low pressures owing to the co-nonsolvency effect. Increasing the pressure reduces the x-range for forming aggregates and leads to the formation of loose aggregates or even to a state of dispersed chains at some x-range. These findings indicate that increasing the pressure can weaken or even offset the co-nonsolvency effect in some x-range, which is in good agreement with the experimental observations. Quantitative analysis of the radial density distributions and radial distribution functions reveals that, with increasing pressure, (1) the densities of both polymers and co-solvent molecules within aggregates decrease, while that of the solvent molecule increases; and (2) the effective interactions between the polymer and the co-solvent weaken, whereas those between the polymer and solvent strengthen. This enhances the incorporation of solvent molecules within the chains, thereby weakening or even suppressing the chain aggregation. Our study not only elucidates the regulatory mechanism of pressure on the microscopic chain conformations and aggregation behaviors of polymers, but also may provide theoretical guidance for designing smart polymeric materials based on mixed solvents.</p></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"43 10","pages":"1929 - 1938"},"PeriodicalIF":4.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242619","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}

By employing self-consistent field theory (SCFT) to calculate the phase diagrams of block copolymers, one can accurately predict their self-assembly behaviors, thus providing guidance for the fabrication of various novel structures. However, SCFT is highly sensitive to initial conditions because it finds the free energy minima through an iterative process. Consequently, constructing phase diagrams using SCFT typically requires predefined candidate structures based on the experience of researchers. Such experience-dependent strategies often miss some structures and thus result in inaccurate phase diagrams. Recently, artificial intelligence (AI) techniques have demonstrated significant potential across diverse fields of science and technology. By leveraging AI methods, it is possible to reduce reliance on human experience, thereby constructing more robust and reliable phase diagrams.

To address the critical gap of insufficient antigen boosting in sustained-release vaccine platforms, we engineered an ultrasound-responsive hydrogel (URH) with diselenide-functionalized 4-arm PEG-ONH₂ (4-arm PEG-Se-Se-ONH₂), 4-arm PEG-ONH₂ and ODEX.

With the multiple boost release mode triggered by ultrasound, the immune response in lymph nodes was significantly stronger than that in sustained release group without ultrasonic trigger. At the same time, it also greatly improved the humoral immunity level, URH+US-OVA elicited 7.5×10⁴-fold higher anti-OVA IgG titers over commercial Al-OVA vaccines and 440-fold higher than URH-OVA vaccines at day 40 post-vaccination, while the levels of blood routine and inflammatory factors were within the normal range, which proved that the safety of URH vaccines.

PCD was generated by thermal treatment of poly(ethylene glycol) (PEG) at the same elevated temperature. To elucidate the structural characteristics of PU-CD, as well as its precursor components PU and PCD, a comprehensive suite of analytical techniques was employed, including transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), dynamic light scattering (DLS) and X-ray photoelectron spectroscopy (XPS).
