Abstract

This study reveals an innovative combination of polyvinylidene fluoride (PVDF) polymer membrane with nanostructured Zn_0.3Co_0.7Fe₂O₄ magnetic fillers that enables photo- and sonocatalytic degradation of organic dyes. Our findings demonstrate that additional coating of Zn_0.3Co_0.7Fe₂O₄ nanoparticles functionalized with polyethylene glycol (PEG) increases the crystallinity of the PVDF matrix and reduces phase separation, thereby enhancing sonocatalytic degradation of methylene blue (50.4% degradation compared to 25.8% for composite with bare nanoparticles). However, the insulating nature of PEG limits photocatalytic activity. These findings highlight the complex interplay between microstructure and catalytic performance, emphasizing the importance of comprehensive material characterization for composite performance tuning.

聚乙二醇表面改性磁性纳米颗粒对PVDF复合材料声催化和光催化的影响

该研究揭示了聚偏氟乙烯（PVDF）聚合物膜与纳米结构Zn0.3Co0.7Fe2O4磁性填料的创新组合，使有机染料的光催化和声催化降解成为可能。我们的研究结果表明，在聚乙二醇（PEG）功能化的Zn0.3Co0.7Fe2O4纳米颗粒上附加涂层增加了PVDF基体的结晶度，减少了相分离，从而提高了亚甲基蓝的声催化降解（降解50.4%，而裸纳米颗粒复合材料的降解率为25.8%）。然而，聚乙二醇的绝缘性质限制了其光催化活性。这些发现突出了微观结构和催化性能之间复杂的相互作用，强调了综合材料表征对复合材料性能调整的重要性。

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
