Effects of PEG surface modification of magnetic nanoparticles on sonocatalysis and photocatalysis in PVDF composites
This study reveals an innovative combination of polyvinylidene fluoride (PVDF) polymer membrane with nanostructured Zn0.3Co0.7Fe2O4 magnetic fillers that enables photo- and sonocatalytic degradation of organic dyes. Our findings demonstrate that additional coating of Zn0.3Co0.7Fe2O4 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.
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.
